-# Skeleton -- a Kanboard plugin template
+# TweakDrag -- board drag, touch and column-gap tweaks
 
-A minimal, working Kanboard plugin that you copy and rename as the starting point for a
-real plugin. By itself it does only one trivial thing: it renders the word "Skeleton" at
-the top of every page. It changes no data and runs no database migration.
+A Kanboard plugin that groups board dragging and spacing tweaks, configurable under
+"Settings -> Tweak Drag":
 
-## What it demonstrates
+- **Drag the board background to scroll** (desktop) -- click and drag on the empty board
+  background to scroll the columns sideways, like the Trello board canvas.
+- **Widen the gap between columns** -- spread the columns further apart, easier to tell
+  apart and to touch.
+- **Mobile drag handle size** -- enlarge the card drag handle Kanboard shows on mobile so
+  it is easy to grab with a finger.
 
-- A complete `Plugin.php` registration class with all the metadata Kanboard shows in
-  Settings -> Plugins (name, description, author, version, homepage, compatible version).
-- A template hook (`template:layout:top`) that injects a template into the page.
-- Asset hooks (`template:layout:css` and `template:layout:js`) that load a stylesheet and
-  a script. They are empty for now but prove the injection path works -- handy when a real
-  plugin needs custom CSS or JS.
-- The standard plugin directory layout, with stub folders (`Controller/`, `Model/`,
-  `Schema/`, `Locale/`, `Test/`) ready to grow into.
+These options were originally part of the ShrinkVertically plugin and moved here so that
+drag/touch behaviour can grow on its own (planned: mobile drag-to-move cards, and a drag
+movement threshold so ending a drag does not open the task) without bloating that plugin.
+
+## How it works
+
+- **Drag to scroll**: a small script (`Asset/js/drag-scroll.js`, loaded only when the
+  option is on) starts a horizontal pan on `#board-container` only when the press lands on
+  empty background -- pressing a task card, a drag handle or any control is ignored, so
+  Kanboard's own card and column drag-and-drop keep working unchanged.
+- **Column gap**: the board is a table, so the gap is set with `border-spacing` (injected
+  in the page head from `Template/layout/variable.php` only when the option is on), sized
+  by the `--td-column-gap` CSS variable. This spreads the columns without shrinking the
+  cards and keeps each column header aligned with its list. It also adds some spacing at
+  the left and right edges of the board.
+- **Mobile drag handle size**: Kanboard already supports dragging cards on mobile, but only
+  via a small handle (a FontAwesome `fa-arrows-alt` glyph it reveals on touch devices) that
+  is hard to grab. FontAwesome icons are sized by `font-size`, so a single rule scales the
+  handle from the `--td-handle-size` CSS variable. It is inert on desktop, where Kanboard
+  keeps the handle hidden.

 ## Installation
 
-No build step and no dependencies.
+Copy this folder into your Kanboard installation as `plugins/TweakDrag/`. The directory
+name must be exactly `TweakDrag` (Kanboard derives the plugin namespace from the folder
+name). No build step and no database migration.
 
-1. Copy this folder into your Kanboard installation as `plugins/Skeleton/`.
-2. Reload any page. The word "Skeleton" appears at the top.
-3. Confirm it under Settings -> Plugins.
+## Settings
 
-To uninstall, delete `plugins/Skeleton/`. Nothing else is left behind.

-## How to fork this into a new plugin
-
-1. Copy the folder and rename it, e.g. `plugins/MyPlugin/`. The folder name must match the
-   namespace and start with a capital letter.
-2. In `Plugin.php`, change the namespace from `Kanboard\Plugin\Skeleton` to
-   `Kanboard\Plugin\MyPlugin`.
-3. Update the metadata methods (`getPluginName`, `getPluginDescription`, `getPluginAuthor`,
-   `getPluginVersion`, `getPluginHomepage`, `getCompatibleVersion`).
-4. Update the hook target paths: the lowercase prefix in `'skeleton:layout/header'` and the
-   `plugins/Skeleton/Asset/...` asset paths must match the new plugin name.
-5. Replace `Template/layout/header.php` with your real template, or attach to a different
-   hook. See the Kanboard plugin hooks documentation for the full list of hook points.
+- **Column gap in pixels** -- width of the column gap (`--td-column-gap`). Default: 25.
+- **Widen the gap between columns** -- toggles the wider gap. Default: on.
+- **Drag the board background to scroll horizontally** -- toggles the Trello-style
+  click-and-drag panning. Desktop (mouse) for now. Default: on.
+- **Mobile drag handle size in pixels** -- size of the mobile card drag handle
+  (`--td-handle-size`). No effect on desktop. Default: 20.
