How do you get into that tiling config? I found it at one time but now I can’t seem to figure out how to bring it up.

Edit: found it, Meta-T.

And then shift dragging works for snapping.

You have to hold the Shift key while moving a window for it to snap into the tiles you set up. If you just move them normally they have a different snapping behaviour like what you described.

@danjay have your cursor snap like at the middle - i think it is like ‘bro is real low so he wants to snap down in this corner, right’
