Request: Indicator for which color channel you're looking at during playback

[fredfx1957]

I Want to use Screen to QC shots and it would be really helpful if there was some way that the user could see what color channel they're looking at when they select R, G, or B when looking at a specific color channel. One suggestion might be a 2 pixel line around the edge of the image in either the color of whichever color channel is selected. # #
