There might be some other updates to make to the diagram in light of recent changes, e.g. introduction of CSSListItem interface. And should traits be included in the diagram (e.g. CommentContainer)?

No, as far as class structures are concerned, traits do not really exists - for example, instanceof does not recognize traits. With this perspective, they are an implementation detail to avoid copy'n'pasting code.

Yes, indeed. Would you be willing to take care of that?

I have no suitable tool. All I'd be able to do is commit a change on a branch, and see how it looks on GitHub...

Actually, that's what I do too. 😉
