@YaLTeR i tested it briefly in a niri winit session with kitty i wasn't personally bothered by the 1st and 3rd listed limitation of non-xray mode it may be worth mentioning in the docs that some programs have blur disabled in their own settings by default. when i first opened kitty there was no blur and i thought it wasn't working properly otherwise good work
if i'm bullshitting and don't know feel free to correct me but it seems really restrictive if you do anything other than game or use a browser or video player
