You can change the default zoom on centering
You can also also change a few things on a “per location” basis for oddities and special cases.
When you right-click on a map pin and choose to edit the place, it has a scaling choice. I do not know if that is persistent but it’s worth experimenting.
(I haven’t experimented because I don’t like that interface and dismiss it quickly. My use of that ‘edit’ is usually by mistake while looking for the standard Edit Place dialog to review the list of References.)
The other thing you my do is change the GPS center coordinate for Chile. Use a weighted center or the capitol instead.
The country centerpoints tend to be irritating because they indicate a region rather than a point … yet they have the same shape as pins marking a precise location. So you see it and think “what Event happened THERE in the middle of nowhere?”
Most of my Events are located in the US. So I changed the US pin to be just offshore Washington DC in the Atlantic. That way, the guesswork Events that were just narrowed to the nation don’t obscure anything.
