Originally posted by AThousandYoungGood idea, but you can do that fairly easily already.
Sometimes I want to go to my clan challenges list and only look at the progress of those challenges I am playing in, but I can't tell which ones I am in because there are so many. A little flag for this would be nice.
In My Games and My Archives, apply the clan filter (optional, you can just search visually either) and go into one of your clan games. There, above the board, you can click on results, which shows how the clan challenge is going.
Not the most elegant of solutions, but it is possible.
hope it helps,
