Add a break-button in tournaments (take glass water, go to bathroom))

It would be great to have a break-button in a tournament, just to have enough time between the games to take a glass water or to go to the bathroom.
Something around 15-45 seconds, perhaps only availible once a tournament.

There's one, it's called "withdraw". You can join back.

Okay, sry. thought it would kick me out off the tournament so I never tried "withdrawl", can you erase the thread?
