[Feature] - Set max zoom level

[Lostdotfish]

I have noticed that when clicking on the map to navigate a short distance, the map autozooms very close in when Autofocus current location is turned on.

This makes it hard to keep track of the wider area that you are testing in and makes it hard to know where you are.

It would be useful if we could limit how close the map will zoom when Autofocusing.
