Feature Request: Big Picture Mode: differentiating between Linux and other games
I actually rather like the fact that you can see *all* your games in Big Picture Mode. However, as things are, it shows all the games in an equal manner while you would not be able to play a bunch of them because they are on Windows (or Mac). This is especially annoying because about half of my game collection has Linux versions that just aren't on Steam yet (so they'll fail to run saying "Not available on your platform").
The same goes for the store, which simply displays *all* games for sale right now, without making this distinction right away. At this point, people might end up buying games they might never even be able to play.
Make it clear right away in the game selection menu that unavailable games can't be played. Like make the icons grey, or maybe a bit smaller, or add an icon in their corner that indicates Steam Play or compatible OS versions.
Add an extra category to the game selection list. Like:
* Recent Games (with greyed out unavailable ones)
* All Games (for your platform)
* All Games (on all platforms)
