It would also be nice if TTTs were built into the interface.

So you just have a "Do a TTT" button and it puts you straight into the weekly TTT competition with a team of bots. All the times and split times are on a leaderboard within the game.

Or maybe you could choose a course and it would show the split times of anyone else that has ever done it before.

You could also have an "Invite friends to a TTT" button where you pick a time and it contacts specific friends or everyone you follow.

With an option to fill empty spots with bots.
