I sort mine by genre, plus a couple categories that overlap with others like "Space" or "No Killing" because sometimes I get in the mood for a particular quality. I don't have an active category, instead I uninstall games that I don't see myself playing in the near future and then use the "Ready to Play" button to see the active ones. Installing games encourages me to do something else, and the limit on how long it'll be helps, "Do chores for an hour while your game installs" is a lot easier for me than just "Do chores." Ideally, I try to limit my installed games to 10 so that I think more about what I actually want to play, I'm not always disciplined about it.
