Originally we were going to include a favourite button. Where it essentially downloads the game, and appears under "my projects" in a favourites section. You would also be notified of updates to that project etc.
But we had to scrap it since we ran into issues. It's still planned, we'll look into adding it as part of our upcoming hub refresh.
(We don't want to go feature overboard as that will increase the time it takes to release the update)
