One big idea that git should learn from Mercurial is history editing. git has only clunky, modal interactive rebase, and struggles with natural questions like "what is the child of this commit."

But hg makes it easy to walk up and down a stack, putting fixes in the right place.

At the risk of overreach, this feature would lead to better software. If your tools have better support for preparing a stack of commits, then code review will be easier, and software will be higher quality.

I wrote git-prev-next to scratch my itch but IMO git should embrace it as a core feature. http://github.com/ridiculousfish/git-prev-next
