Let us change the background color of the Program Monitor :')

As is possible in AE, it would be a very nice addition to be able to temporarily change the program monitors background to a desired color instead of black.

I know, I know, “create a matte and underlay it..”

Yes, but: AE can do it too and it makes a lot of sense as a safety feature against having accidental tiny black margins, which can easily happen if you work with letterboxed footage, or the transform effect (does not show clip frame-outlines, as changing scale in “Motion” does).

Best, L
