Don't know if there's such a sort already (If so I'd like to know how to use it)...
Is there a sort for "Recent Purchases"... or perhaps "Recent Installs". (sometimes I get something new and then... can't find it... this would be nice.
Also, because large library lists take forever to scroll through - and because a hiccup in an install can auto-scroll you back up to the top of the list.... it would be nice to have a toggle view "Purchased/Installed vs. Purchased/Not installed" (something like Apple has for apps).
