Thanks for the feedback! I actually want to have it on mobile as well but will most likely choose React Native instead of trying to make the web app work on mobile (or maybe only with some very simple functionality). At first, my approach was to have a planner on desktop and route viewer/navigator on mobile, but you're right - there needs to be an option to update/modify your route while traveling.

Regarding state: it's only a matter of changing the blacklist array in redux persist config. Right now I have all global state blacklisted because I noticed a small bug with rendering the map layers when the state is persisted and I didn't have time to fix it but in the next version it will be persisted in localstorage.
