First of all, I find the web version such a great tool for planning trips and routes, thank you. I have used it a lot and find the planned routes to be excellent...I'm always recommending this to friends.

A question/request.....I seem to find it very easy to accidentally change the loaded route in the app when zooming and panning around on the screen of my android phone. Is there, or could there be, a way to lock the route to stop any accidental changes? Secondly on the web version, could there be a "Redo" button, so that when trying out slight changes to the route, it is possible to both "Undo" and "Redo" changes?

Thank you.
