It would be nice if we can import text files in the following format and have it determine who's connected to whom in the right way.
FN = First Name
My_FN Dad's_FN Granddad's_FN GG_FN ... Last_Name
Cousin's_FN Uncle's_FN Granddad's_FN GG_FN ... Last_Name
Thus, if it find's a sequence of similar names in a line, it would identify them for you and ask you if you wish to merge them.
I don't have much in terms of dates or other data for now since I'm still building the tree names. This would be useful for those who are just starting with a tree and wish to connect them. A maternal one could also be added.
