Progress on the front-end started last weekend and is going well so far. Be sure to follow @Mucx (me) and @OpenEmu on Twitter for more updates.
Fingers crossed, it looks like we will be able to add 'Collections' to OpenEmu after all in the 'New UI'.
Collections operate in the same manner as playlists in iTunes allowing you to group and organise games to suit your tastes. This required that a smart collection and standard collection sidebar icon be drawn up... and here they are.
