Allow stretching on repeated keystrokes

[sboardwell]

Hi and thanks for the app. I'm new to MacOS and this was a lifesaver. I was wondering if the option of stretching and shrinking on repeated presses has been discussed.

The app already has actions for repeated keystrokes so perhaps this could be added.

The benefit would be that you would only need the cursor keys to achieve the majority of positions instead of needing to remember multiple combinations.

On Linux, pressing super + up on a window which is already moved left, for example, would place it into the top left corner, pressing down would stretch it back to full screen, and down again would put it in the bottom corner. Pressing up on a window which already top and full width would maximize the window, up again brings it back to half, leaving you to press left or right again to put it into the corner.

A picture is worth a thoudand words so I've created a GIF to illustrate.
