Created attachment 115082 [details] Quick concept of the feature In Windows 10, there's a really nice feature where if you snap a window to one side of the screen and another window to the other, a separator is made between them that allows you to drag and resize both windows at the same time instead of grabbing one, resizing it, and then grabbing the other and resizing it to match. I'd love to see something like this in Kwin if possible.
There's a script available on store.kde.org.
As Martin said, there is a script to do that. To install that go to System Settings > Window Management > KWin Scripts, click "Get New Scripts..." button and search for "Sticky Window Snapping". Also, I suggest to try Chris Holland's (Zren) modified version of that script: https://github.com/Zren/kwin-script-sticky-window-snapping
