I use AltDrag on Windows (requires a quick tweak for HiDPI): https://stefansundin.github.io/altdrag/
And Easy Move + Resize on MacOS: https://github.com/dmarcotte/easy-move-resize
That's awesome, I remember when I was a CS student in college I also fell in love with the alt+drag of windows on Linux and I wanted to bring the same on my Windows PC so I wrote this extremely hacky and very unstable tool: https://github.com/Morgawr/EmptyWM
It was one of my first "open source" projects and a great learning experience, I would never recommend anyone to use it because it was full of bugs (also I haven't touched it in like 10+ years) but I used it every day and it was such a great feeling just being able to improve my own life with tools I created myself. :)

Put me in the camp that hates window snap/tiling.
I have a certain workflow that needs this window there, and this one here ... don't snap to a location or go full screen.
