Position displays with arrow keys
In the Displays section of the settings app, it would be nice to have fine control of relative monitor positions using the arrow keys.
For example, I have three monitors: Two monitors of the same size easily snap-align horizontally (awesome) but the third is smaller and in "Portrait Left" orientation. When moving the monitor boxes with a mouse, it's hard to get the boxes to perfectly match reality (so that a cursor moves between displays at the same exact height).
