This [1] is a nice AHK window manager. Win+UpLeft moves the current window, Win+DownRight resizes it, and WinSpace centers. Makes it easy to compose resizing & moving to get exactly what you need. Vertical is 50% increments, horizontal has increments at 0%, 33%, 50%, 66%, and 100%, though ofc you can customize cause its AHK. Only works with 1 monitor though.
