Comment 2 for bug 485993

Since, in the new system, lemmas are just one kind of annotation, we
should handle them in the same way we handle other annotations. Here is
how I see it. Right now, I can delete the active word or delete the
lemma annotation. We also have the option 'redo existing annotation'
which can effectively create a different relationship between the active
word and another annotation. So I think the current system works fine
and we probably don't need to add any new features to it, at least for now.
