I'm going to guess this has been brought up before, but I don't know if there are any plans for it. I'd love to see game status added as a search filter. That way, developers can mark their game as "no longer in development" or "currently in development" and users can search for games according to that.
I love playing games on here and giving feedback, but when I'm looking for a game that's actually going somewhere, it can be annoying when it turns out that 80% of the cool ones I found aren't even being worked on anymore. It would save a lot of search time if I could filter those games out to begin with.
