Use non-modal messages when adding new parties
Currently, you can add parties in plotContrib subform, but it asks you "do you have more info about [person] and you have to select yes, no or cancel." It should be more streamlined, I think. The advantage to it as it is now is that you can't add duplicate parties as easily, but it should be less modal.
Perhaps Gmail-ish, where it says "you have added party X" and there would be an "undo" link at the same place.
