It'd be great if I could tag my games using more than one custom category. For instance, I set a custom category for all games that have controller support as "Gamepad" which includes non-Steam games as well. But I would also like to tag some of those games as "Local Co-op" too. Please look into this. It sounds like such a simple feature/idea but I'm sure other people out there would like to filter their games by more than just one category. Thanks!
