@balloni55#160: fixed & improved, thanks
@Andrew Heardhmm, maybe after five years > LoRouter based routes will have set Street name for navigation points!
There is no support regards this "Round trip" feature yet

. 0 points > app will use current map center, 1 point > use this. it then generates a round trip in direction and closes to the defined total distance. Try it, it is simple

Anyway thanks for the nice suggestions in the following post. I'll look at it. I also hope, that Radim finds some time and creates a little more robust in-house solution based on LoRouter that should support what I consider more important - a round trip over at least two (or more) points.
Documentation: don't blame me, it is a task for Michal! And as he does not know what to do sooner (80% of time spent on the help desk), it will take some time ... anyway big "FAQ" blog post will be published this week.
@slarti76thanks for the tests!
Notification about sync, so-called "push notifications" are currently not completely in our control. It is a service from Google that uses "Google Play services" installed in every Google-supported device. So I really hoped, there won't be any troubles to fix ... hmm, your tablet ...
I'll try to play with more devices at once a little later. Currently, I test mainly web & one device.
Switch track <> trackpoints - I'll think about it.
Track editor > added to "Todo"
@Viajero Perdido"Round trip" feature is again something not complete in our control. It is a feature that offers GraphHopper service and it simply allows from a single defined point, azimuth and expected distance, "generate/suggest" a "round trip", nothing more.
