Almost No Need For Sideloading Now

I was reading some stuff over at the Nvidia forums and someone mentioned that they were able to install apps from the web play store onto their Shield, that wouldn't show up in the Leanback Play store. I gave it a try and sure enough I could install a bunch of apps, I even tried completely random ones like catlog and facebook, both installed!

Some things will probably still have to be sideloaded but this is an easy alternative.
