It's good to see that our suggestion has been added, now we have the 15sec and 30sec time span.
According to the management the discussion I had with them a few days ago, they said the site have new skin and new time-frame. I can see the site looks nicer, the cosmetics have been improved. But as far as I can remember there already used to have 15 and 30 seconds time-frame.
BTW they added new stable token and memetoken.
