One thing that always mess me up when I go back to Windows is its way to move and resize windows, I am more used to some windows managers in Linux where you just have to press a key and click anywhere on the window to move or resize it. It is very handy and intuitive, you don’t have to aim for the title bar or anything and do as you please.
Thankfully I recently discovered a wonderful software that does just that: AltDrag
Sadly it has not been updated since 2015, but it does a lot of things already. I urge you to test it as it drastically changes the experience on any computer.
By default the key is set to Alt, but it’s best to put it on Windows (Meta) especially if you do 3D work. You can also change the transparency of windows as well as the “Always on top” and “Borderless” settings.
