I always liked the idea behind Divvy. I like tiling, but i usually dont have more than 3 or 4 windows open at the same time. Most of the time they are one maximized, or two with half the screen each. But sometimes i need to place 3 or 4 in some way, and i think having a tiling window manager just for this rare cases its a little overkill.
Today instead of studying for my exams, i decided to make a Kwin script to simulate the divvy way of manual tiling.
All the instructions of how to install and use it are in the Github repository. But nothing strange, download the kwinscript file and install it from settings. Hit the shortcut, click here, there, hit the shortcut again to hide it and you are done.
