A suggestion..

Wouldn't it be good if a player's connection quality was also shown? It'd be informative for the player, letting them know when they needed to improve connection, but also for potential opponents. 

Personally, I find nothing more frustrating than playing someone whose connection is consistently so bad that it takes 20 minutes to complete an end as their rock meanders up the ice, a meter at a time.

I doubt anything will happen as a result of this but it made me feel better writing it :p
