This release adds tabs, to deal with the increasing number of listed games. Installed games are now put in a separate tab, and when you click a game to install you are moved to the “Installed” tab to see its progress.
Each tab remembers its position and search/sort settings independenty though, so switching tabs won’t disturb your browsing.
The program now also consumes much less CPU while idle (ie. while games are running), which is always a good thing. Here are some comparison screenshots (click to enlarge):
