@Andreas_Hegenberg Floating windows are great (pin function) especially after your last improvement.
But they always float above everything. But sometimes I would like them to float just above the other windows of their app (A). So when I switch to app (B) I want them to stay in the background and when I switch back to (A) I want them to still float.
unfortunately macOS doesn’t have a way to modify window levels in that way. However it might be possible to only float a window on top while the window‘s app is in foreground.
