Make tiling a first-class citizen
There are countless tiling plugins (KWin scripts, all of which break in Wayland sessions) for KWin. The feature is obviously desired, but as things stand, using them requires ugly hacks like:
- tweaking window decorations
- ensuring windows are never natively maximized
- ignoring size hints in some programs like system settings
It would be nice if this feature was more accessible and only a toggle away like it is in Pos!_OS. Tiling window managers aren't just for technical users. That's a consequence of how difficult they are to set up. And KDE isn't Gnome, leaving every tweak to plugins. Something like Krohnkite integrated into KDE would bring tiling to the casual Linux user, where it belongs.
The ability to hide window decorations and add borders indicative of the active window regardless of style (breeze/oxygen/etc.) would also be a prerequisite for this feature IMHO.
