There's two things hg blame doesn't do which would be useful.

First, the trivial one.  I don't want lines annotated by change number, 
I want them annotated by the name of the person who checked it in.  But, 
I'm sure that can be easily fixed with some simple post-processing 
filter, so it really falls into the bucket of "minor annoyances".

The hard thing is I don't really want to know which change most recently 
touched the line of text.  I want to know who really wrote it.  It would 
be wonderful if hg were smart enough to be able to back-track through 
the change history and ignore trivial changes like whitespace, 
refactoring a function out of one file into another, etc.  That's the 
real meat and potatoes of "blame".  I want to know who I need to hit 
over the head with a clue-by-four once I fix a bug.
