Thanks, that makes sense!
I guess the only thing is about loops (basically, roundabouts) - if you have
A--B--C
| |
F--E--D
and you split at A, I guess nothing happens, but if you split at D do you end up
with
A--B--C--D D--E--F--A ?
Which might be a bit confusing because "A" will be an arbitrary point somewhere
else on the roundabout.
Otherwise, sounds great!
