option to split the zoom focus between the current and previous panes only

[RyGuyCMT]

Hey great plugin. I love it.

The one thing I would love to see is the option to split the focus between only the active pane and the previously active pane.

I work with 4 panes open and organize my files by many different criteria. When I swap focus, the current pane is set to the current zoom setting (which I love), and the other panes are distributed evenly amongst the rest of the space. I don't get much functionality out of that with 4panes side to side. I don't personally like the 4 quadrant look, and can't imagine that this same behavior is any more functional there.

I'd love to be able to set the focus zoom to ~50% and have the current pane and the previous pane be split 50:50 (or 60:40, if I set the zoom to 60) and the remaining panes minimized as much as possible.

I hope this request makes sense.

Thanks for the great plugin.
