It's incredible to use, especially in concert with Magnet (a window management app). Three-finger-drag a window to the top of the screen and it's instantly maximized. Selecting text is also a breeze.
Sounds like a lot of work compared to any good tiling window manager. Windows should be automatically maximized on opening, unless there are others on the desktop, in which case just hitting a two finger key chord should do it without requiring contorting a wrist or moving an entire forearm away from the home row.
I do most of my window rearranging when I'm switching workflows or connecting an external monotor.
I really hope Ubuntu and friends get "inspired" by all the touchpad gestures in macOS.
