Here’s a first-pass mockup of pedigree navigation I’ve been working on
Basically you can go backward and forward between generations, starting from the initial person. No support yet for going to siblings or other children not on the direct line from the starting point. That will come later.
I’m trying to do this all in DHTML. The closest equivalent I’ve seen is the flash-based viewer from familysearch labs. I have no experience with flash/flex myself, and I’d rather stick with open technologies if possible.
Tested in FIrefox 3, IE7. May work with other browsers, but no promises…
