[Marble-devel] Review Request: Elevation Profile Plugin

[Konrad Enzensberger]

Hi Bernhard,

>>Moreover, I'm also not sure how manual rotation should be triggered.

I like  to use the rotation for beeing able allways driving upwards in routing guidance mode.
So may be anywhere in the PositionMarker plugin would be the right place to calculate heading
and trigger rotation automatically,

what do you think about ?

Will you merge the rotation changes to git master ?

br, konrad
