It would be really useful in group rides where there is a ride leader / beacon to have that rider pinned at the top of the rider list on the right of the screen. This then makes it a lot easier for people to know how far in front or behind they are. They can also see the w/kg that the leader is putting out which could be useful if you’re trying to match the pace or catch up.
This might also help with people flying off the front as they can see how far behind in seconds the leader is, more so than what they get now.
