In plasma you can stitch a window to a half or a quarter of one of your monitors.
Once a window is tiled this way, plasma tracks it in a special manner. You can move the window back to its initial size by dragging it and if you change the size of a stitched window all windows stitched to the desktop resize at the same time.
So far so good. Now, the problem is when you stitch more than one window on the same corner or half window. There is no easy intuitive way to navigate between windows stacked in the same place.
I understand Plasma knows there are more than one window stitched to half a screen or a quarter of screen. It would be great to detect it and show an icon in the menu bar to circle though them when (and only when) it detects that more than one windows are attached to the same corner/half monitor/full monitor.
While that was requested specifically for the Custom Tiling (Super+T) feature, I’d imagine the same navigation methods could then potentially be used for quick-tiled windows as well - that could be a way to accomplish the goal that it sounds like you’re getting after?
That would be the goal, but it is difficult and I am not sure anybody is going to develop it in KDE 6 as it might break too many things. That is why I thought that cicling or having a button to launch expose would be easier to develop options.
