Great theme, been using this for a month and really like it, thank you! Just noticed one possible bug, "Arrange by" doesn't work in details and list view, it always defaults to A-Z no matter what you choose. Or is it just supposed to be that way, haven't really those two views before.
Edit: Also in list view, when you select a random game with Ctrl+Alt+Q, would be nice if the list scrolled down/up to the chosen game. Now it just stays in one place, and doesn't move at all to focus to the chosen game like it does in image and details view.
