You're welcome! (again :-)
I'm pleased to say that we've now added an option to turn off the pop-up instructions for the Plot functions, so you can disable them once you're familiar with how they work. This new option can be found in your Settings (click on the cog in the top right corner of the route planner to access your Settings).
Thanks again for suggesting this John.
Mmm! Good suggestion. There's no way to stop the pop-up instructions at present but I'll add it to the feature request list to provide an option for doing this. Thanks for the feedback.
... every time I use the "Replot section" I get a pop-up telling me what to do. I've used it quite a lot now so know how to use it. Can I make it stop popping up? I'm logged in, if that helps make settings easier to save.
