You can add a vertical or horizontal splitter as an item under the tabs, you can then mount various components and toolbars under that splitter just like the rest of your layout. I once built a layout where everything except for a control bar at the bottom was switched .. and I used that to switch betwen several different layouts.
I tried that, but for some reason it wouldn't work. I'll try again, maybe things will go better this time.

Nope, still doesn't work.
