1. When doing "Search Records" there should be the option to exclude records already attached to the person. Indexing is providing new records occasionally it would be nice to be able to search them without needing to wee through the records that have already been attached.
2. I'd like to see a "bread-crumb" style indication of how to get from the ancestor I am currently looking at back to me. When you are many generations back and your ancestors have many children, it can be very difficult to click your way back up the tree to yourself. I think a little icon or some indicator next to the ancestor that is in your direct line would be nice.
3. A relationship calculator. I want to be able to tell if this is my third cousin, twice removed, or what not.

Thanks,
Bret
