Request for 2/3 center

[floriandulzky]

Idk if it was already discussed (couldn't find it).

I am working on a wide-screen and I very often use the feature "1/2 center" and then increase the window (with the "larger" feature) to roundabout 2/3 of the screen size.

It would be very nice to do this within a single shortcut.
