Love the new layout, so much better than the old one. There's just one thing that really bother me:
The map view when editing courses is way too small. On a 1920x1080 display, the map view is only using approx. 1775x493 px. That's not even 50% of the available height.It's even less when elevation is shown.
Suggestion: Reduce the white border around the map, 30 px should be enough. Also enlarge the map view so it's using most of the available screen resolution.
