Hi!
Seeing this project had gotten an update recently, I wanted to test it, but came across an annoying bug.
I get an empty "ghost" tile and when I move my focus (windows mouse focus, clicking the empty area) and pressing mod+y, I have a pop-up with ApplicationFrameWindow as the Window Class.
Testing with hashtwm -i ApplicationFrameWindow successfully gets rid of the ghost tile. I hereby recommend that this ignore rule should be baked in to the executable or mentioned in the ReadMe.
I'm running Windows 11 Insider Beta build, if that is relevant to the issue.
Here's what it looks like on my PC:
