I tried to use this feature (Gramps 3.1.1 from SVN, Windows Vista, IE7) but:
- I do not have a data-views variable in keys.ini file. I did a manually copy, but it doesn't help to see the new tab for Geoview in Preferences.
- Is there any where a geoview.py for download??
Seems to me that you need an HTML kit for having !
geoview.py for Gramps 3.1.1 should be on your /DataViews directory. Also is available there !
