Smarter diff tool

Sorry if this is frowned upon but I just wanted to point out a feature request that I'd really like to see implemented.
My latest comment on it doesn't appear to show up here in the forums (just on the tracker discussion list) so I wanted to post this here and encourage everyone who would like to see a smarter diff tool to go vote.
