^Reminds me that Steam needs better wishlist management... Can't change the order of the games when you have any filters active, including text search, and Ctrl + F doesn't work, and best of all, the position on the wishlist is not shown when any filters are actived, so you can't manually scroll to a game either. And before any of you asks, I do order my wishlist, or at least the top part of it. I've actually written a (buggy but functional enough) userscript to help me with this, which I'm sure Valve appreciates, since it keeps the whole wishlist loaded at once (the 'vanilla' wishlist unloads everything that's not visible at the moment).
Also, that's an insane number of games! I'm terrified enough of my Steam library of 500+ games, most of which I've never touched, I'm sure, but over 5,000? Wow - and I know you actually play a lot of games too!
