-### Features
+> **Upstream credit:** All core functionality — widgets, theming, layout engine, hot-reload — is the work of the [Glance](https://github.com/glanceapp/glance) project and its contributors. This fork adds an editing UI on top and nothing else. If you find Glance useful, consider [sponsoring the upstream project](https://github.com/sponsors/glanceapp).
-#### Various widgets
-* RSS feeds
-* Subreddit posts
-* Weather
-* Bookmarks
-* Hacker News
-* Lobsters
-* Latest YouTube videos from specific channels
-* Clock
-* Calendar
-* Stocks
-* iframe
-* Twitch channels & top games
-* GitHub releases
-* Repository overview
-* Site monitor
-* Search box
 
-#### Themeable
+> **⚠️ Vibe coded:** The editing UI in this fork was built entirely with AI assistance and has not been rigorously tested. It may have bugs, edge cases, or security issues — particularly around config file handling. Use it on a trusted network, keep backups, and don't be surprised if something breaks. PRs welcome.
-![multiple color schemes example](docs/images/themes-example.png)
 
-#### Optimized for mobile devices
+---
-![mobile device previews](docs/images/mobile-preview.png)
 
-#### Fast and lightweight
+## What's added
-* Minimal JS, no bloated frameworks
-* Very few dependencies
-* Single, easily distributed <15mb binary and just as small docker container
-* All requests are parallelized, uncached pages usually load within ~1s (depending on internet speed and number of widgets)
 
-### Configuration
+### In-place edit mode
-Checkout the [configuration docs](docs/configuration.md) to learn more. A [preconfigured page](docs/configuration.md#preconfigured-page) is also available to get you started quickly.
+A pencil button in the dashboard header toggles edit mode. While active you can:
+- **Drag and drop** widgets between columns and reorder them
+- **Add widgets** via a form dialog (for most widget types) or a YAML editor fallback
+- **Edit widgets** inline with per-field forms — includes live lookup for weather locations, market symbols, and RSS feed validation
+- **Delete widgets**
+- **Add, delete, resize, and reorder columns**
+- **Add and manage head widgets** (the row above the columns)
 
-### Installation
+### Page management (`/edit`)
-> [!CAUTION]
+- Add, delete, and reorder pages
->
+- Per-page settings: name, slug, width, navigation options, mobile header
-> The project is under active development, expect things to break every once in a while.
 
-#### Manual
+### Site settings (`/edit/site-settings`)
-Checkout the [releases page](https://github.com/glanceapp/glance/releases) for available binaries. You can place the binary inside `/opt/glance/` and have it start with your server via a [systemd service](https://linuxhandbook.com/create-systemd-services/). To specify a different path for the config file use the `--config` option:
+- App name, logo, favicon, footer — all editable without touching YAML
 
-```bash
+### Theme settings (`/edit/theme-settings`)
-/opt/glance/glance --config /etc/glance.yml
+- Color pickers for background, primary, positive, and negative colors (hex input, stored as HSL)
-```
+- Contrast and text saturation multipliers
+- Light mode toggle, hide-picker toggle, custom CSS file path
+- **Preset management**: add, edit, and delete named theme presets with live preview swatches
+- **Built-in theme catalog**: 14 themes from the upstream docs (Dracula, Catppuccin variants, Gruvbox, and more) importable with one click
 
-#### Docker
+### Multi-step undo
-> [!IMPORTANT]
+`/edit` keeps a 10-step numbered backup chain (`glance.yml.bak.1` … `.bak.10`). Each save rotates the chain; any backup can be restored individually.
->
-> Make sure you have a valid `glance.yml` file in the same directory before running the container.
 
-```bash
+### Auth gate
-docker run -d -p 8080:8080 \
+`/edit` returns 403 unless `auth.users` is configured **or** `admin.allow-without-auth: true` is set. See `docs/glance.yml` for examples of both.
-  -v ./glance.yml:/app/glance.yml \
-  -v /etc/timezone:/etc/timezone:ro \
-  -v /etc/localtime:/etc/localtime:ro \

+## Installation
+
+### Docker (recommended)
 
 ```yaml
+# docker-compose.yml
 services:
   glance:
-    image: glanceapp/glance
+    image: ghcr.io/uhlwoogi/modern-glance:latest
-    volumes:
-      - ./glance.yml:/app/glance.yml
-      - /etc/timezone:/etc/timezone:ro
-      - /etc/localtime:/etc/localtime:ro
     ports:
-      - 8080:8080
+      - "8080:8080"
+    volumes:
+      # Config dir — glance.yml lives here and is written by /edit
+      - ./config:/app/config
+      # Optional: custom CSS / images (set server.assets-path: /app/assets in glance.yml)
+      - ./assets:/app/assets
     restart: unless-stopped
+    # environment:
+    #   MY_SECRET_TOKEN: abc123   # reference as ${env:MY_SECRET_TOKEN} in glance.yml
 ```
 
-### Building from source
+1. Create the config directory and grab the starter config:
-
-Requirements: [Go](https://go.dev/dl/) >= v1.22
-
-To build:
-
    ```bash
-go build -o build/glance .
+   mkdir -p config assets
+   curl -o config/glance.yml https://raw.githubusercontent.com/uhlwoogi/modern-glance/main/docs/glance.yml
    ```
 
-To run:
+2. Start:
+   ```bash
+   docker compose up -d
+   ```
+
+3. Open `http://localhost:8080` — click the **pencil icon** in the header to start editing.
+
+> The starter `glance.yml` has `admin.allow-without-auth: true` so `/edit` is open by default. Switch to the auth block in the file before exposing to a network you don't fully trust.
+
+### Updating
 
 ```bash
+docker compose pull && docker compose up -d
+```
+
+---
+
+## Original Glance features
+
+Everything from upstream is intact:
+
+- **Widgets**: RSS, Reddit, Hacker News, weather, YouTube, Twitch, markets, Docker containers, server stats, bookmarks, calendar, monitors, and [many more](docs/configuration.md#configuring-glance)
+- **Fast and lightweight**: low memory, minimal JS, single ~20 MB binary, pages load in ~1s
+- **Highly customizable**: multiple layouts, pages, themes, custom CSS
+- **Mobile optimized**
+- **Themeable**: tweak a few numbers or pick from the [theme gallery](docs/themes.md)
+
+Full configuration reference: [docs/configuration.md](docs/configuration.md#configuring-glance)

+
+## Examples
+
+The best way to get an idea of how the templates work would be with a bunch examples. Here are the most common use cases:
+
+JSON response:
+
+```json
+{
+  "title": "My Title",
+  "content": "My Content",
+}
+```
+
+To access the two fields in the JSON response, you would use the following:
+
+```html
+<div>{{ .JSON.String "title" }}</div>
+<div>{{ .JSON.String "content" }}</div>
+```
+
+Output:
+
+```html
+<div>My Title</div>
+<div>My Content</div>
+```
+
+<hr>
+
+JSON response:
+
+```json
+{
+  "author": "John Doe",
+  "posts": [
+    {
+      "title": "My Title",
+      "content": "My Content"
+    },
+    {
+      "title": "My Title 2",
+      "content": "My Content 2"
+    }
+  ]
+}
+```
+
+To loop through the array of posts, you would use the following:
+
+```html
+{{ range .JSON.Array "posts" }}
+  <div>{{ .String "title" }}</div>
+  <div>{{ .String "content" }}</div>
+{{ end }}
+```
+
+Output:
+
+```html
+<div>My Title</div>
+<div>My Content</div>
+<div>My Title 2</div>
+<div>My Content 2</div>
+```
+
+Notice the missing `.JSON` when accessing the title and content, this is because the range function sets the context to the current array element.
+
+If you want to access the top-level context within the range, you can use the following:
+
+```html
+{{ range .JSON.Array "posts" }}
+  <div>{{ .String "title" }}</div>
+  <div>{{ .String "content" }}</div>
+  <div>{{ $.JSON.String "author" }}</div>
+{{ end }}
+```
+
+Output:
+
+```html
+<div>My Title</div>
+<div>My Content</div>
+<div>John Doe</div>
+<div>My Title 2</div>
+<div>My Content 2</div>
+<div>John Doe</div>
+```
+
+<hr>
+
+JSON response:
+
+```json
+[
+    "Apple",
+    "Banana",
+    "Cherry",
+    "Watermelon"
+]
+```
+
+Somewhat awkwardly, when the current context is a basic type that isn't an object, the way you specify its type is to use an empty string as the key. So, to loop through the array of strings, you would use the following:
+
+```html
+{{ range .JSON.Array "" }}
+  <div>{{ .String "" }}</div>
+{{ end }}
+```
+
+Output:
+
+```html
+<div>Apple</div>
+<div>Banana</div>
+<div>Cherry</div>
+<div>Watermelon</div>
+```
+
+To access an item at a specific index, you could use the following:
+
+```html
+<div>{{ .JSON.String "0" }}</div>
+```
+
+Output:
+
+```html
+<div>Apple</div>
+```
+
+<hr>
+
+JSON response:
+
+```json
+{
+    "user": {
+        "address": {
+            "city": "New York",
+            "state": "NY"
+        }
+    }
+}
+```
+
+To easily access deeply nested objects, you can use the following dot notation:
+
+```html
+<div>{{ .JSON.String "user.address.city" }}</div>
+<div>{{ .JSON.String "user.address.state" }}</div>
+```
+
+Output:
+
+```html
+<div>New York</div>
+<div>NY</div>
+```
+
+Using indexes anywhere in the path is also supported:
+
+```json
+{
+    "users": [
+        {
+            "name": "John Doe"
+        },
+        {
+            "name": "Jane Doe"
+        }
+    ]
+}
+```
+
+```html
+<div>{{ .JSON.String "users.0.name" }}</div>
+<div>{{ .JSON.String "users.1.name" }}</div>
+```
+
+Output:
+
+```html
+<div>John Doe</div>
+<div>Jane Doe</div>
+```
+
+<hr>
+
+JSON response:
+
+```json
+{
+    "user": {
+        "name": "John Doe",
+        "age": 30
+    }
+}
+```
+
+To check if a field exists, you can use the following:
+
+```html
+{{ if .JSON.Exists "user.age" }}
+  <div>{{ .JSON.Int "user.age" }}</div>
+{{ else }}
+  <div>Age not provided</div>
+{{ end }}
+```
+
+Output:
+
+```html
+<div>30</div>
+```
+
+<hr>
+
+JSON response:
+
+```json
+{
+    "price": 100,
+    "discount": 10
+}
+```
+
+Calculations can be performed on either ints or floats. If both numbers are ints, an int will be returned, otherwise a float will be returned. If you try to divide by zero, 0 will be returned. If you provide non-numeric values, `NaN` will be returned.
+
+```html
+<div>{{ sub (.JSON.Int "price") (.JSON.Int "discount") }}</div>
+```
+
+Output:
+
+```html
+<div>90</div>
+```
+
+Other operations include `add`, `mul`, `div` and `mod`.
+
+<hr>
+
+JSON response:
+
+```json
+{
+  "posts": [
+    {
+      "title": "Exploring the Depths of Quantum Computing",
+      "date": "2023-10-27T10:00:00Z"
+    },
+    {
+      "title": "A Beginner's Guide to Sustainable Living",
+      "date": "2023-11-15T14:30:00+01:00"
+    },
+    {
+      "title": "The Art of Baking Sourdough Bread",
+      "date": "2023-12-03T08:45:22-08:00"
+    }
+  ]
+}
+```
+
+To parse the date and display the relative time (e.g. 2h, 1d, etc), you would use the following:
+
+```
+{{ range .JSON.Array "posts" }}
+  <div>{{ .String "title" }}</div>
+  <div {{ .String "date" | parseTime "rfc3339" | toRelativeTime }}></div>
+{{ end }}
+```
+
+The `parseTime` function takes two arguments: the layout of the date string and the date string itself. The layout can be one of the following: "RFC3339", "RFC3339Nano", "DateTime", "DateOnly", "TimeOnly" or a custom layout in Go's [date format](https://pkg.go.dev/time#pkg-constants).
+
+Output:
+
+```html
+<div>Exploring the Depths of Quantum Computing</div>
+<div data-dynamic-relative-time="1698400800"></div>
+
+<div>A Beginner's Guide to Sustainable Living</div>
+<div data-dynamic-relative-time="1700055000"></div>
+
+<div>The Art of Baking Sourdough Bread</div>
+<div data-dynamic-relative-time="1701621922"></div>
+```
+
+You don't have to worry about the internal implementation, this will then be dynamically populated by Glance on the client side to show the correct relative time.
+
+The important thing to notice here is that the return value of `toRelativeTime` must be used as an attribute in an HTML tag, be it a `div`, `li`, `span`, etc.
+
+<hr>
+
+In some instances, you may want to know the status code of the response. This can be done using the following:
+
+```html
+{{ if eq .Response.StatusCode 200 }}
+  <p>Success!</p>
+{{ else }}
+  <p>Failed to fetch data</p>
+{{ end }}
+```
+
+You can also access the response headers:
+
+```html
+<div>{{ .Response.Header.Get "Content-Type" }}</div>
+```
+
+<hr>
+
+JSON response:
+
+```json
+{"name": "Steve", "age": 30}
+{"name": "Alex", "age": 25}
+{"name": "John", "age": 35}
+```
+
+The above format is "[ndjson](https://docs.mulesoft.com/dataweave/latest/dataweave-formats-ndjson)" or "[JSON Lines](https://jsonlines.org/)", where each line is a separate JSON object. To parse this format, you must first disable the JSON validation check in your config, since by default the response is expected to be a single valid JSON object:
+
+```yaml
+- type: custom-api
+  skip-json-validation: true
+```
+
+Then, to iterate over each object you can use `.JSONLines`:
+
+```html
+{{ range .JSONLines }}
+  <p>{{ .String "name" }} is {{ .Int "age" }} years old</p>
+{{ end }}
+```
+
+Output:
+
+```html
+<p>Steve is 30 years old</p>
+<p>Alex is 25 years old</p>
+<p>John is 35 years old</p>
+```
+
+For other ways of selecting data from a JSON Lines response, have a look at the docs for [tidwall/gjson](https://github.com/tidwall/gjson/tree/master?tab=readme-ov-file#json-lines). For example, to  get an array of all names, you can use the following:
+
+```html
+{{ range .JSON.Array "..#.name" }}
+  <p>{{ .String "" }}</p>
+{{ end }}
+```
+
+Output:
+
+```html
+<p>Steve</p>
+<p>Alex</p>
+<p>John</p>
+```
+
+<hr>
+
+In some instances, you may need to make two consecutive API calls, where you use the result of the first call in the second call. To achieve this, you can make additional HTTP requests from within the template itself using the following syntax:
+
+```yaml
+- type: custom-api
+  url: https://api.example.com/get-id-of-something
+  template: |
+    {{ $theID := .JSON.String "id" }}
+
+    {{
+      $something := newRequest (concat "https://api.example.com/something/" $theID)
+        | withParameter "key" "value"
+        | withHeader "Authorization" "Bearer token"
+        | getResponse
+    }}
+
+    {{ $something.JSON.String "title" }}
+```
+
+Here, `$theID` gets retrieved from the result of the first API call and used in the second API call. The `newRequest` function creates a new request, and the `getResponse` function executes it. You can also use `withParameter` and `withHeader` to optionally add parameters and headers to the request.
+
+If you need to make a request to a URL that requires dynamic parameters, you can omit the `url` property in the YAML and run the request entirely from within the template itself:
+
+```yaml
+- type: custom-api
+  title: Events from the last 24h
+  template: |
+    {{
+      $events := newRequest "https://api.example.com/events"
+        | withParameter "after" (offsetNow "-24h" | formatTime "rfc3339")
+        | getResponse
+    }}
+
+    {{ if eq $events.Response.StatusCode 200 }}
+      {{ range $events.JSON.Array "events" }}
+        <div>{{ .String "title" }}</div>
+        <div {{ .String "date" | parseTime "rfc3339" | toRelativeTime }}></div>
+      {{ end }}
+    {{ else }}
+      <p>Failed to fetch data: {{ $events.Response.Status }}</p>
+    {{ end }}
+```
+
+*Note that you need to manually check for the correct status code.*

+## Upgrading to v0.7.0 from previous versions
+
+In essence, the `glance.yml` file has been moved from the root of the project to a `config/` directory and you now need to mount that directory to `/app/config` in the container.
+
+### Before
+
+Versions before v0.7.0 used a `docker-compose.yml` that looked like the following:
+
+```yaml
+services:
+  glance:
+    image: glanceapp/glance
+    volumes:
+      - ./glance.yml:/app/glance.yml
+    ports:
+      - 8080:8080
+```
+
+And expected you to have the following directory structure:
+
+```plaintext
+glance/
+    docker-compose.yml
+    glance.yml
+```
+
+### After
+
+With the release of v0.7.0, the recommended `docker-compose.yml` looks like the following:
+
+```yaml
+services:
+  glance:
+    container_name: glance
+    image: glanceapp/glance
+    volumes:
+      - ./config:/app/config
+    ports:
+      - 8080:8080
+```
+
+And expects you to have the following directory structure:
+
+```plaintext
+glance/
+    docker-compose.yml
+    config/
+        glance.yml
+```
+
+## Why this change was necessary
+
+1. Mounting a file rather than a directory is not common practice and leads to some issues, such as creating a directory if the file is not present, which has tripped up multiple people and caused unnecessary confusion
+2. v0.7.0 added automatic reloads when the configuration file changes, which based on testing didn't work when mounting a single file
+3. v0.7.0 added the ability to include config files, so you'd have to make this change anyways if you wanted to take advantage of that feature
+
+Taking all of these into account, it felt like the right time to implement the change.
