Maximize window vertically

[ghosty141]

Briefly describe how the feature should work

When dragging a window to the top/bottom edge of the screen (not in the corners) it should maximize the window vertically. This behavior exists on the windows tiling application too.

Explain why this feature should be added

I run an ultrawide screen, fully maximising is often too much, it's generally more useful to have the main window sit in the middle but maximized vertically.
