“View as role” with option to see what’s restricted

One thing I’ve noticed with the new(ish) “view as role” feature is that while it is helpful with seeing what a user can’t see, it can still be difficult and tedious trying to figure out what channels a user can’t see. Having an something like a toggle while using the view as role feature that shows the channels you can’t access in a color like dark gray would help in figuring out what channels that role can’t see, useful for if you actually wanted that role to see that channel and did not know they couldn’t.
