It would be great if lap splits were identified on the HR graph. A simple line shown at each lap point would be useful... perhaps as a toggle option like how you can currently check a box to show avg HR on the graph. Even more useful would be to highlight each lap on the graph as it's selected in the splits section.
I just started using laps to aid in my training and would love to be able to identify these on the HR graphs. Also as a follow up showing the total elapsed time with the lap splits would be great, I know there's a seperate link for that request but the two seem to go hand in hand.
