Timer (Countup)

It would be cool if we could have a timer (shown on the screen) that would count the time we spend on a game (the count-up timer, not the countdown). It would also be cool if the time we spent on individual round would be shown too (maybe on the score screen (alongside with the time we spent on the whole game)). Now there are a lot of people who are measuring how much time they need for different things, and this would be extremely useful. Right now people must use third-party tools and means to count the time spent on games and rounds.

Another good thing would be adding a countdown timer that would count the time down for a game as a whole (all 5 rounds under one timer), instead of for individual rounds. This means we will be able to spend different amount of time on differently challenging rounds, but would still have a countdown timer for the total.
