Wait, what. There's a niche for this? Well I was way off on what I originally thought your concept was, lol.

I actually really like that idea. That could also be done in small tiles as well where it could be displayed below the panel you're currently viewing in a thumbnail-like grid. Right? I'm no programmer but that could conceivably be an easy way to do something like that and even have the panel you're currently viewing have a highlighted border around the small thumbnail below. Edit: I haven't even drawn here yet. Lol. Art block is a cruel mistress.
