Additional fields for display styles

Would it be possible to add disambiguation notice into the common knowledge section? It doesn't need to display the full text, just (say) the first couple of lines with a 'more' button. It's useful when there's different versions of the same work with significant differences: e.g. audiobook vs dramatised audio or an abridgement or a collection sharing the name of a short story.

Another wishful pony is adding work relationships, specifically the 'Contains' relationship. This is useful to add missing relationships.

Lastly, a sortable last edited date for your book. (By you, of course.) We now have the edit history, so hopefully that should be easy!
