I knocked out a couple of features and pushed to the beta leagues just now:
1) Game Center now remembers zoom and speed. This will be persistent to your account, so even after you log out or change computers it should remember your settings.
2) If you are in one of the beta leagues you will notice a new 'ignore' button on forum threads. This will automatically mark those threads as read, which will eliminate the green dot/menu notification. The only caveat to this is that the thread has to also be updated from one of the beta leagues ... so if you ignore a community thread now, it won't fully work until this update has gone across all leagues.
This may get pushed to all leagues as soon as this weekend if there are no problems.
