It would be keen to be able to use the Relationship tab to find the distant relationships on different sides of a family line, not just the current method of show only one line back.
Chris mentioned this was on a to-do list a while back in this thread http://www.wikitree.com/g2g/64567/is-this-a-bug-in-the-relationship-finder and I want to re-express interest in this improvement.
Being able to retrieve one more, several more, or eventually even all relationships would be an awesome improvement to Wikitree!
