I also agree with OdinsPlayground regarding the black boxes around each game. It would be nice to have it transparent.
Also, in the current LaunchBox, hovering the mouse cursor over a game would bring up a nice little bar where you can quickly access game art, flip the box to display the back cover and other things. I hope we will be getting that back as I like using it for easy access of the game art without having to go into a sub-menu.
