# wlmaker - Roadmap

Vision: A lightweight and fast Wayland compositor, visually inspired by Window
Maker, and fully theme-able and configurable.

Support for visual effects to improve usability, but not for pure show.

See the [Detailed Feature List](FEATURES.md) for details.

## Window Maker features

## Overall

* Window attributes
  * Build and test a clear model for `organic`/`maximized`/`fullscreen` state
    switches and precedence.

* Application support.
  * Icons retrieved and used for iconified windows. See [themes](https://specifications.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html).
  * Make use of XDG Desktop Entry [specification](https://specifications.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html).

* Configuration file and parser:
  * Support different background styles (fill, image).
  * Make semicolon-after-value required, for consistency with GNUstep.
  * Theme.
    * [done] Added ADGRADIENT fill style, aligned with Window Maker's diagonal.
    * Adds support for textures as fill (tiled, scaled, maximized, centered, filled?)
    * Add drag-modifier option, to configure when a drag makes a window move.

* Configurable keyboard map.
  * Verify support of multi-layout configurations (eg. `shift_caps_toggle`)
  * Support ChromeOS layout switch hotkey (`Ctrl+Shift+Space`)

* Configuration tool, similar to WPrefs.

* Compositor features
  * Bindable hotkeys.
  * Pointer position, to support apps like wmscreen or xeyes.

* Commandline flags to support:
  * icon lookup paths beyond the hardcoded defaults.

* Reduce Technical Debt
  * Move the setenv calls for DISPLAY and WAYLAND_DISPLAY into subprocess
    creation, just after fork. These should not impact the parent process.
  * subprocess_monitor: Use listeners, not callback.

* Exploratory ideas
  * Stretch: Consider supporting XScreenSaver (or visualization modules).

## Visualization and effects

* Animations
  * Launching applications, when *starting*.
  * Size changes (maximize, minimize, fullscreen).

* Task switcher
  * Application icons or minimized surfaces to visualize applications.
  * Animations when switching focus.
  * Clean up signal handling (emit on task switch, enable, disable).

* Resizing & moving
  * Consider visualizing windows partially transparent when resizing or moving.

## Dock Apps

* Sensors.
* Clock
* System tray.
* CPU load.
* Network monitor.
* Laptop battery status.
* Julia set.

## Non-Goals

* Do not (re)create a GNUStep environment.
* Creating a dedicated toolkit.
