That thing Windows has where you can drag a window to the top of the desktop and it pops up a few quick options for resizing. I would love it if KDE Plasma had this.

I'm fairly certain (an earlier iteration of) that came out in Windows Vista which is nearly 20 years ago. It was called Aero Snap.

I didn't know that. I actually used Windows until 2019 and only learned about this feature last week. Well, that does it: UI has only gotten worse.

you can also hold down the windows key and use the arrow keys to position the window left/right top left/top right/bottom left/bottom right.

And Windows-shift-up to make a window fill the vertical space of the screen without changing its width.
