I run a daily challenge, and for each round I like to shout out the person who got closest. Currently I need to either estimate which pin was closest (which isn't always obvious) or scroll through the leaderboard and try to figure out who was closest, which is messy. It would be easier (and more accurate) if for a specific round, we could sort by distance, putting those that were closest for that round at the top of the leaderboard. I would imagine this could be implemented by adding a simple button next to the round number at the top of each column.
