Hi Michaël,
Thanks a lot for the improvements. However, I would like to ask you to help
with one more fix. Now the script fires the requests automatically and it is
dangerous if user has selected a layer with thousands of features. Could you
show how to limit the maximum number of requests to 10? Generally it is good to
be able to do several routings at a time because it gives a simple way for the
user to use interim fixed route points by digitizing the route as connected
lines but I think that 10 legs should be enough.
