So there isn't a way to do a horizontal list unless you set it in vertical mode, but leave the monitor oriented horizontally. That's a bummer.
Hmm. Well I could always just do one big image in the center of the screen and just have an up & down arrow on the top & bottom of the image indicating how to scroll through the games.
What other front ends would you recommend to more easily setup that kind of layout? Maybe Maximus? I wouldn't mind trying hyperspin, but it seems pretty intimidating to dive into.
