This page lists a few ideas of simple tasks to be implemented in KWin. If you want to work on one, please check with the KWin team whether anybody is working on it already. If you need help on your task you can always contact the KWin team.
See also Trello board for further tasks.
KWin provides window tiling which is hardly maintained and unknown to the core KWin team. The idea behind this task is to reimplement the tiling functionality as a KWin Script. This has several advantages: tiling gets properly decoupled from KWin core reducing the maintenance costs for the core team. It would also proof that KWin Scripts are powerful enough to implement a complete new window management concept.
KWin's settings are partially described by kconfigxt which would allow to move the configuration modules (KCM) to be generated from KConfigXT.
The AnimationEffect provides easy ways to define animations for windows. This could be extended to allow uploading a vertex and/or fragment shader which is used when rendering a window. The AnimationEffect would in that case animate a uniform value of the shader.
After OpenGL 3 Support has been added to KWin the Shader Manager should be extended to support Geometry Shaders.
After Geometry Shader Support has been added to KWin it should be possible to use a Geometry Shader to calculate the Geometry for Wobbly Windows Effect.
After Geometry Shader Support has been added to KWin it should be possible to use a Geometry Shader to calculate the Geometry for Magic Lamp Effect.
One of the main window management UIs of the KDE Plasma Workspaces are Present Windows and Desktop Grid. Unfortunately the user has to know about it and the configuration interface is very hidden. In this small project a dedicated configuration module should be written to configure Present Windows and Desktop Grid.
KWin could need improvments for the default options. For example there is a default of one desktop. This implies that if the user changes to more desktops we can expect that he wants to use it. So desktop grid should be enabled by default.
