I tried them all: Magnet, Rectangle, Yabai, Raycast window management, maybe something else I forgot. I have no clue how I only learnt about Loop today. It seems to have a combination of features that works best for me personally:

- triggered by Globe key (both radial menu and shortcuts)

- radial menu below the cursor

- two arrows at the same time for different action

- properly visible preview.

I have high hopes to live happily ever after with Loop.
