Nice. Things that would make this even better:
1) Go through the first four generations and show only those individuals who are missing information. This could be missing a death date or missing a source for a death date. Then this would be targeted to helping me fill in missing information.
2) Allow me to enter research notes, to keep track of what I have done so far, and what records I have looked at.
3) Allow me to save people I'm working on into various todo lists or projects ("my English ancestors", or "my ancestors from Shoreditch").
4) Give me some indication of progress -- what I did over the past month, how many records found, sources attached, people completed, etc.
