Just tried it. On the 24 inch monitor, I had 3 windows open and it perfectly tiled them. I used to use divvy and it was all manual, so this is great improvement. Plus one for auto focus.
Note: In case someone is wondering, to give accessibility access, check the checkbox for terminal in the security and privacy --> accessibility settings
Did the keyboard shortcuts work for you? I can't get them to work (even tried adding some flags to check whether they are being caught or not and they don't seem to reach hotkeys.so's code, ever, for me)
