Problem: As I build bigger compositions, I find it difficult to manage both computation cost, and items on the screen.
A workaround is to use a Select Output node on the output and input of a subcomposition, but that doesn't clear the image/last frame. It's also rather clunky, and I'm sure not as efficient as things could be.
What I'd love is a boolean control on sub compositions (and optionally on all other nodes??) which I can set to OFF, resulting in absolutely no processing, and a nulling of the frame or other output.
