Comment 9 for bug 1269148

building on top of #2575 I'll change the 'Passthrough' overlay to a QLabel that can be styled independently from other overview texts (Loading, Analyzing ...).
Hope it's easy to make that translucent, stack it on top of the overview and allow mouse events on the overview. This would suffice the 'short on decks' usecase, wouldn't it?

When someone manages to implement a live overview other features like live recording and then manipulating the recording are obvious, like lp:1407222, and we can add a Deck / Live switch that swaps Deck / Live overview & controls.
