This is perhaps a tangential issue, perhaps not:

None of the annotate text UI, gannotate, or qannotate address a use case I
commonly have: when in trunk did this line change?  The dotted revno only
gives me a lower bound for that answer, which is barely useful.

It's very good that they can tell me the original revision that changed a
line, but I frequently also (or only!) wanted to know when it changed in a
particular branch (typically bzr.dev).
