The "My Games" page has been returned to its former general layout, and the "inbox" is back.
Things to note :
The contents of your inbox will not be as it was prior to the first update yesterday. If your games had not already been placed in custom folders :
The Inbox folder includes all incomplete games.
The Archive folder includes all completed games.
But games can be placed in any folder, should you choose, much like before.
Some features from the now abandoned My Games are still included though, such as archive to any custom folder and the enhanced collapsible sidebar.
