I think some kind of save / dump to a file or to a sqlite database that could be imported would be AWESOME.
I agree with the sentiments of losing the work / time of a multi-hour scan.
Obviously all the standard disclaimers would apply about files might have changed, yada yada yada.
Having a scan run for a few hours and not having a checkpoint if you lose that work is a serious bummer.
Recuva is a great product and has helped me out quite a bit.
