Works great for me. I enabled that functionality alongside resizing on RMB by using "Easy Move+Resize" from GH. I also use Raycast to bind most window management stuff, it's instant unlike the built-in alternatives on Tahoe.

Same, tried with and without Rectangle running and haven't seen it work yet. Must be missing something obvious.

edit: I ended up trying Easy Move+Resize which is mentioned in a sibling comment, can recommend, works as advertised.
