I'm in love with your application, thanks for it.
I believe that it will be very useful to have an option to put just finished game in Favorites directly. For that on the window which appears after each game, between "Share" and "Analyse Board", or above "Share" you can put something like "Put in Favorites (star)". This is important in case you play hundreds bullets/ultra bullet games one after another and want to review some of them later.
You can't post in the forums yet. Play some games!
