Hi,

Personally, option 2+4 has the most appeal to me.

My gut feeling is that this ends up being frustrating to users.

I'm aware of that. The rationale for this was that the annotation dialog is 
mostly used with relatively small subsets of the general pictures. I.e. you 
invest the time in small chunks instead of a single multi-hour investment.

Having a config option seems reasonable - you can enable the gps search by 
default for new users only. Re-reading the exif db could also enable gps 
search.

You don't even need to make it a checkbox in the settings dialog - you could 
just make it a button on the map widget of the search dialog.
Once you turn it on and complete the exif db transformation, it doesn't make 
sense to turn it off again. Or does it?

That would be an individual feature unrelated to the gps search. I can see the 
value of it, though...


Cheers,
