the smart research is good tool however it seems to be very USA centric.
Firstly, it could do with search options that can be selected as a default but with options if required.
For instance the majority of people in my tree lived only in the UK so searching USA, Canada, Australia etc is a waste of time.
secondly, once a person is "researched" there seems to be no way to start again from scratch, which you might want to do if you had just found some more information about them.
thirdly, it never seems to return any Scottish information, maybe add a few extra extra search parameters for this?
