I have a gaming desktop when I'm home, but I game on a MacBook Pro when I travel. It would be nice to be able to filter my wishlist so I could see only games that support Steam Play.
So, Enhanced Steam is discontinued. There is now Augmented Steam. Perhaps your requested feature/bugfix is already implemented there! If not, you could move your issue there.
