I’ve been thinking for a while about what would make for a great UI to merge 2 records together. For instance, let’s say you have 2 contacts in your contact list, and both are really one and the same. This happens quite a lot for me using Gmail’s contacts as Gmail automatically creates contacts based on people you correspond with, and since quite often friends have more than 1 email address that they use, I end up with “duplicate” contacts in my list.
Gmail unfortunately gives you no easy way to merge these records, and that got me thinking about the best way to handle something like this from a UI point of view, not necessarily just for Gmail (which of course I can’t change!) but for any system in general.
