Working with an active navigation route was the one area where I felt they could improve. In particular, the UI for cancelling guidance is too small and fussy. I'm probably not the only one who noticed because it looks like they reworked some of that.
I am NOT optimistic about how they appear (in 8.0) to be hiding the main navigation at the top. Doesn't seem like the extra space was ever needed. It feels like a cosmetic decision that adds an extra step.
