I'll probably maintain it on Github principally for issues/PR but I'll try my best to maintain both, if anything contact me on twitter @y4my4my4m.

• KDE Store: https://store.kde.org/p/1413010/
• Opencode: https://www.opencode.net/y4my4my4m/kde-shader-wallpaper

• Version 1.0 - Simply load shaders
• Version 1.1 - File Dialog added
• Version 1.2 - iGPU fix
• Version 1.3 - 70 new shaders + autolisting
• Version 2.0a - Customize shaders via GUI, directly load shaders from shadertoy.com or file (current version)
• Version 2.0.1a - Breaking bug fix regarding the pause/fullscreen feature(current version)
• Version 2.x - Save/Load edits, better customization, better buffers/channel

• GUI Customization is highly experimental, bugs will occur.
• Shadertoy.com imports doesn't work on all shaders, that is because iChannels/Buffers are not fully implemented yet
• Performance may vary depending of your specs, but it's actually not all that resource intensive, depends on the shader too.
• If you modify the shader files and want to see the changes, the KDE Wallpaper QtQuick App itself needs to be restart, I recommend simply to pkill plasmashell and restart it.
