One side note: The "Note" layout to expand on functions seems suboptimal to me. It is not easy to discern among the notes which belongs to which. It would probably be helpful to have better fledged sections under the form (function_name => more notes).
As Tom mentions nearby this has been significantly improved upon in the upcoming version. While v13 is still in Beta you will find that for reference tables its documentation is far superior. And given the nature of these changes, i.e., non-bugfix, enhancements to older versions are not likely to be forthcoming for this particular observation.
