Yeah, good isn't it. I setup a course for an "exploring" run the other day and some might be interested in this pic https://www.instagram.com/p/BF_gCGouofB/ which gives an idea of the sort of display you get.
I think the second alert is a confirmation that you made the correct turn. I actually like that as sometimes if you get no feedback you are not sure about the turn unless you are watching the bread crumb map.
