Thye did implement a decent game list (where you could assign a game to multiple categories) when the beta started but one of the first updates got rid of it for the collapsable lists instead - there's quite a big list of people complaining on the steam beta feedback forums, but there hasn't been a single reply from any of the steam staff to say if they've taken the complaints on board (which has also raised complaints). At the moment the game list is less than useful. Edit: Click on the magnifying glass in Steam. the customisable games list isn't that customisable tbh. When the beta first started you could assign games to multiple categories and just show games from particular categories, so for example Borderlands could be assigned to FPS, RPG, Single-player, Multi-player, Co-op, In Progress and Favourites. Filtering to any of those categories would bring up Borderlands. At the moment filtering has been removed, and you can only assign a game to 1 category which is pointless, a lot of games will fit into more than 1 category. Can't understand why they removed that functionality - it worked a lot better than the system they have implemented now.
