Hello fellow KDE users! I use KDE Plasma on my tablet, but found windows managements a bit painful when using only the touchscreen, so I wrote this KWin script: it just organize automatically each window in a separate virtual desktop, maximized and borderless, allowing you to use the built in touchscreen gestures (3 fingers slide) to switch between them (animations are real smooth!)
I also released it on pling/kde store

Hope you’ll find it useful! Let me know your thoughts about this!
