"Open Quickly" (Cmd_Shift_O) resets current panes state
Detailed steps to reproduce the problem:
- Create some panes (splits) be it vertical or horizontal
- Maximize such a split (Cmd_Shift_Enter)
- Try "open quickly" for any of the panes you've just made
What happened: maximization's gone, all the panes are downsized and shown at once.
What should have happened: user's current layout for panes shouldn't be changed. Just proper (requested) pane should be made active, that's it.
