A few people requested this and I can’t find the thread, but here is what the update will be hopeuflly this will help or solve the problem.
How about coloring HR (and Power) chart according to the zone?
Something similar to what Intervals does:
Much more visual than numbers…
No way 
I would say like Zwift does. But no. Sorry, at least not for power. Heart rate I am contemplating new design ideas.
I am more interested in HR zones coloring.
Thank you for considering this!
