Just like the title says. I want to add my non-steam games to the list of all/installed games in big picture mode, instead of giving them a separate tab.

I know you can create a collection but that doesn't create an all games tab. It just creates a collection in the "collections" tab. It makes sense to also create a "non-steam" tab but, the "all games" tab should have ALL GAMES.

I don't want to minimize what developers do. I'm not saying this is an "easy" thing to implement. I'm not a developer, I have no idea how difficult this is. But I AM saying that the word "all" should mean ALL. Especially now with SteamOS becoming a contender in the "all in one" gaming PC space, this is a no-brainer.
