This is kind of what I was thinking of as well. The checkpoint list will 
probably have to work the same way the new search result list works with a 
few checkpoint related options. We'll have to wait for feedback on the 
search list in the next release to see if this'll work well. Once the list 
is implemented then the basics like point moving and goto shouldn't be too 
I think there'll have to be some smart logic to figure out the starting 
point and direction when a route is activated with the ability for the user 
to override the automatic choice. Figuring out what direction along the 
route to go might be a bit tricky.
The automatic point adding probably won't be too hard. These would probably 
have to be stored as checkpoints only rather than in the main database until 
they're renamed to something more useful.
The ability to check a point when it's added is on the todo list. The only 
thing difficult about this is the symbian user interface programming rather 
than the loadstone code itself. I'd just like to have another field in the 
point entry form that's a checkbox of some kind to enable the point as a
