Clarify magnetic vs true directions
In the sky view, there is an arrow that is obviously for some kind of North. It is really not clear which North it is. Perhaps, if the sensor page is labeled, and this is the same, then it doesn't need labeling.
In the sensor page, there is "azimuth". It is not labeled true vs magnetic. If it is true, it is not clear where the magnetic model comes from.
(This issue is solely about labeling the current behavior.)
