Pretty good feature and worked! Perfect, and no login to the account required.
But one thing is a con.
Steam has a feature called: Profile Features Limited (or Learn about this game before)These games don't count to the Game counter and statistics. And so this Launcherbox system can't import these games in this list.
I mean, many of these are trash, but some good, and manually is preeeeeeetty much work, because I missed 1000+ games with this feature in my library.
