Feature Request

Please add an option to mark and filter games by "owned". It would also be nice to have markers similar to "favorite" on the main interface for "owned" as well as "completed"
(I use the site http://www.completionator.com/ for this now, and it's cool but leaves much to be desired)

Another cool feature would be to have the option to enable all official releases for a console that you don't have roms for yet as greyed out that you can still look at basic info on them via launchbox.
