Until the last one hundred years, most people spent their entire lives in the same location, or a location closed to where they were born. It would save users a lot of typing if you could simply click a button next to the place of death fields to fill in the corresponding fields from the place of birth location, and vice versa. You could then edit any fields (such as the Place name or City) that need to be changed.
You could also provide buttons for "Same as place or birth" and "Same as place of death" beside the location fields for place of marriage and place of burial as well. For the vast majority of people who lived before WWI, at least 3 of these 4 locations will be identical or nearly so.
While it's true that you can cut and past from one location to another, when you do this, all of the info goes into a single field (Place name) instead of into the appropriate individual fields. This results in locations that are poorly formatted, and more importantly, in less efficient searches.
I know this may seem like a trivial request, but as someone who's recovering from a broken wrist and is aware of every single keystroke and mouse click, let me assure you that it would be greatly appreciated by users, especially by those with carpal tunnel, arthritis, or other disabilities. Even people who don't suffer from any of these afflications would benefit by being able to enter data faster and with fewer errors.
