Right now, "Not done" inline comments are peppered across many source files. They are hard to find. It would be really helpful if there was a consolidated section of "Not done comments" so the author knows what is left to work on before the diff can be submitted.

At the same time, it's hard for the reviewers to keep track of what comments they've already made, and what comments are still "Not done" when they go back to a diff to re-review.
