I'd like to see the layer router embedded in each layer control, with ability to turn it on/off.
When it is turned on you would be able to control the incoming video input as well any slices it is connected to in advanced output.
If Layer 6 has text and is routed to a single slice on 4 different screens, I would like to be able to turn the slice off on the layer side, instead of opening advanced output to turn it off.
