One of the features I used often in MapSource was the ability to select a route and drag it onto a different road than the one chosen by the program's routing algorithm. When I did this, MapSource would create a new waypoint to designate where I'd moved the route. With BaseCamp, I have to create a waypoint separately, then add it to the route in the correct location between existing waypoints.
I participate in motorcycle endurance rallies, and I'll often get over 100 waypoints designated by the rallymaster that I will load into my mapping software (either MS or BC). These will designate the origin and destination of many possible route segments. I'll often have to adjust the exact route from one to the next as I've described, but the BC method forces me to go searching for my newly created waypoint among the many already loaded. Mapsource let me simply drag the route where I wanted it and continue on with my planning.
Thoughts?
