Is it possible to turn off the day markers on the output map?
On the map produced in the itinerary? I don't think it is - they don't show on the PDF output though IIRC
It wouldn't be that difficult to allow for them to be turned off. The danger is that programs like this end up with so many options asked for by different people that they become fiendishly complicated for new users.
Persuade me why being able to turn them off would be a good thing, and I'll do it!
