Very often when using a dual display, I'd like to resize the width of one of the two displays, making one file display smaller and the other bigger. I know I can just hover over the separating line between the displays (or edge of the tree if I'm using dual tree view), but it would be neat if I could make this "selection" with a mouse shortcut, meaning the separating line would snap to wherever my cursor is (with some clamping to whatever is acceptable).
Is there some way to do this, or how could I set this up?
For reference, I'm talking about similar behavior that you get when resizing windows, that happens when you press the following in a non-maximized window:
alt + space
right arrow + down arrow
-> now the bottom right corner of your window goes to wherever your mouse is.
