Martin actually just committed an initial implementation for tags. I
know it is one of his primary items, and he seems to actually be working
on it now. :) (He has a commit message on bazaar-commits about
implementing a first draft of tags)

I thought Olive had a built-in diff between revisions. Specifically the
same diff as provided by 'bzr gdiff' (when you install bzr-gtk). And the
same one that shows up when you double click a line in 'bzr gannotate'.

I suppose he is asking to be able to spawn a third-party diff program.
But we have basic for that in the 'difftools' plugin, which will likely
be merged into core. (bzr diff --using meld).
