I too think that the map in GC is crappy. The map field is too small. It should be possible to resize it.
Another, for me very important thing, is the ability to see laps correctly.
I have a run that is 10 km. Autolap for every 1 km.
If I check the activity in GC and mark that I want to see laps, i get a marking on the map for 1,3, 5, 7 and 9 km.

Also it could be really cool to have the possibility to get km markings also. So markings per lap and per km. So if I am doing a 3x2 km split, I still have to option to mark out the single km distance.
+1 for this. It's vexing that the elevation, speed, etc. charts have zoom buttons, but the map doesn't. Out of everything on the page, isn't the map the part that most people would want to be able to make bigger?
Also agree with the bigger map option. And it would be nice if the graphics with heartbeat, speed etc could be shown on one screen and the map on a second screen.
