I'm not sure if the current solution of making everything invisible until I decide to install it at which time it will show up in my library is going to be the permanent solution because being hit with 1700+ items would be a bit overwhelming. But for the time being at least, we can only search the list by title. Going through 1700 items manually is just not a feasible task for most of us. I for one have very little idea of what I've bought so having the ability to search by tag or keyword would be fantastic. This way I can start to get a grasp of what's in this bundle.
