It would be great if the maps/directions notifications appear directly without the need to touch on screen to see the proper notification. And it could make a better use of the double screen, the upper showing arrows or signs and the bottom showing directly the information, like, the name of the street, bus stop, or short commands when in trails, turn left, return.
Just as a sugestion to think about in next updates.
The watch is great, it could be smarter on maps notifications.
