I am aware of the feature that allows you to see your friends on the minimap or in the rider list (if they are within 6 places of your position) but I think there should be something that shows which riders on the main screen are your friends. The challenge is that in many of rides, everyone is wearing the same kit and riding similar bikes. Additionally, there are riders constantly pulling ahead and falling behind. This makes it hard to see and keep track of your friends in a event or group ride.
It would be cool if maybe your friends names would always show above their avatar or if there was a “star” above the riders head. That way, you could easily assess where your friends are in a group. The minimap shows an approximation of where your friends are but it would be helpful to see their specific position.
