Very first and preliminary test result:

At first, I was confused. I had my geocoding preferences set 
none/none/none, but I could see that something was done because the 
location tag changed to location tags (//) when hitting the new icon. I 
first verified the changes in my git log, and saw the tags being added.

Obviously, this is just my user error :-) but it might be better not to 
show the location tags line in case of a preferences setting that does 
not show anything.

Yes, and this solved my confusion :-)

Clicked around all over the world, and even found the name of farmers 
range in the middle of the Mexican jungle (and yes, that range has a 
cave on site). I could not make it crash or report funny things (that 
can be attributed to Subsurface, and not the used geocoding service)

So very happy at this point.

best,
