Some ideas:
- Make it possible to collapse / expand the map and remember that setting - if a user has collapsed it don't run the code to generate the map on future loads .
- A full screen mode would be great (especially when trying to add a location)
- You can add location by appending wikitext in a save.
- In the cases of pages without a location show the world map - showing anything more accurate is probably too difficult.
- The edge menu would be interesting if it appeared within the article content - maybe in a right gutter which pushes the article content to the left - this would also help with the Typography Refresh !.
