I just discovered this amazing project. I have been looking for such a program for years. Thank you!!!!
I have one suggestion: adding a way to see in game screen shots easily. A couple of ways to do it would be have 2 or 3 screen shot thumbnails pop up when the user mouses over a game or have an (optional) screen shot pane that changes as each game is clicked. Ideally the screenshots could be auto-grabbed from the internet like the other image files. A bonus feature to this would if it could show screen shots taken by the user too.
Regardless, thanks for the awesome program!
