@zossebartah, good observation. Complicated task

. I'll look on it tomorrow, but can't promise. Will probably have to merge line before and after, created from it a route with only three points and change middle point to desired navigation command. Little weird ... :/
@lor74cashmm no back button? One of the most used buttons on Android?? How he control other apps, no problems??
I'm really not sure how useful such a button may be to others ... sounds to me as really useless :/. If he have enabled fullscreen mode (he probably has) then he may also swipe from left to open main menu. Then it's almost no extra work for this one-time task I think. Sorry, I've convinced myself, that such button really does not make sense
