Well, I was thinking of that. You mean like some kind of icon that displays if it's a video or audio file? Because right now it lists them both the same, and when it plays them it determines what type of file it is (audio/video) and treats it accordingly.
I have a nice looking blue bulb graphic that I ganked from FrontRow that I think I could use and it would look nice. But I would only like indiciate movie files with it. I hate the look when it's 10,000 of the same icon, you know what I mean?
Have you tried the photo slideshows? Does it work ok? (mouse click to exit)
