for my eyes the effect of the GPS on/off toggle in the tool bar on top of the map page seems inverted:
If the GPS icon in the tool bar is crossed out, the receiver is on.
If the GPS icon is switched to "on" (no red cross), the receiver is off.
Maybe there is some logic behind this (thich means, that the switch always shows, what you are going to do - not what you have) - but I'm simply getting confused by this.

Kindest regards,
