So many ideas because of three tiny colored dots
@tapiothe issue with a refresh of the track: thanks TODO
With a dual centering button, rotate icon should really be visible, it is intent. With this solution, you may simply disable rotation without affecting centration.
If "dual-mode" needs an extra rotation button was discussed a half year ago a lot and yes, it needs

.
Good sample: center, start rotating, move with the map - now disable rotation in case you do not have this "rotate" button.
@balloni55ah, dot attached to centering button in case, rotation is disabled and dual-centering button is enabled, is a bug, thanks
@luceah, the clickable area behind ... not so simple task => is this really needed? I'm more thinking about and option to put these buttons into function panels - but this also is not so simple task

Rotation mode
I also think that icons should not be so obtrusive. Some small "A", "M", symbols should be enough. I'm waiting on our graphic.
But, the indicator is needed from my point of view. If the map rotates by the GPS, it may not be clear that rotation is enabled. Also if you start rotation of the map manually, it may not be clear that the map won't rotate by sensor anymore.
@Žajdlík Josefthanks, as I wrote to @balloni55, the dot attached directly to the big centering button is a bug, thanks!
