I was thinking that it would be nice to have a rapid-with-increment option in the "Quick Game" menu.
My idea would be to replace the 15+15 (which is *incredibly* slow) with something like 10+5.
My reasoning would be that if someone wanted to play a game that can easily last more than 1 hour (as a 15+15 game can), he probably doesnt need to use the "Quick Game" menu in the first place. And it would just be nice to have a rapid time control with increment for us "slower" players.
Also, if some lichess-dev has access to statistics, I'd be interested to know how popular the 15+15 option is (to confirm or disprove my suspicion that's it's barely used currently) in relation to the other time controls in the "Quick Game" menu.
Let me know what you think of this idea!
