Can I snap windows to fill 1/4 of the screen like in Windows? I know you can 'pin' two windows left/right on Mac through the full-screen option but is there no simple shortcut like on Windows, to resize/move just the current window top/left and bottom/right? In Windows you can easily get up to 4 windows neatly arranged and I am struggling to believe Windows is ahead of Mac in terms of user interface... so how can I do this?
There’s an App that I use to gain the Windows “snap” like functionality in macOS - Magnet

There are a number of configurable shortcuts that allow you to snap Windows in halves, thirds, quarters, etc.  It costs $2USD, but is well worth the price
