I just saw this awesome tip/post on reddit and had to share. Basically, it's a really smart and easy way of adding every game from IndieGameStand to Steam. There's been discussions about not buying a game because it's not on Steam - I think that's sad, but perhaps this solution will help:
"If it's DRM Free, what I like to do is download the games to a folder on my external HDD. (In this case, the folder would be /Indie Game Stand/Bleed/) Then once installed create a category in Steam called Indie Game Stand, and use the "add non steam shortcut" tool to add all my Indie Game Stand games!"
