How so?

I've found steam is by far the best digital distribution client when it comes to managing my game library, mainly because of the 'steam libraries' feature that lets you create a steam library on any hard drive to install games to, and it makes restoring your games on a clean install of windows extremely simple too (just go into steam library settings, point it to the steam library folder(s) on your drives and all your games are back).

Origin and uplay aren't nearly up to par when it comes to stuff like managing games on multiple hdd's.

I have 153 games. Steam's built-in categories seem to be Recent, Installed, Favorites. It'd be nice to be able to sort my library by, say, games with controller support, games with coop, games with multiplayer, etc. (Or further -- say, games with multiplayer and games that support Linux, in case I want to find a game I can play with my friend who games on Linux.) You can add your own categories, but one category per game.

> games with controller support, games with coop

I think you can do both of these in Big Picture Mode.

FWIW, you can now have more than one category per game.
