We can split the screen into two parts (tiling) by snapping two windows left and right. |----|----| We can give one window a bigger share than the other by resizing both windows, one after the other. |----|----| |--| |----| |--|------| It would be nice if both windows could be resized at the same time such that both windows cover all of the screen width. |----|----| click^here while holding shift, then move mouse left |---|-----| |--|------| |-|-------| This could be triggered by clicking+dragging on the middle border, while shift is held, or middle clicking on the middle border. Could also be done vertically, or with a 4 window split when resizing by clicking at the screen center. It could also be triggered for windows which aren't snapped to any screen corner.
