There should be a bug on clicking 'Notes" seems it expanded the functions when I click it.
Thats a great idea to have "Notes" as a separate section. Before doing this change, there is one thing we should take into consideration: Is "Package Notes" a session most other docs would have or for this package only? We have the separator under session title like " Source files" in the captured screen. If most other package docs have the same session, then we can add a new session for "Notes" . If "Note" is for this package only, then I would recommend not adding new pattens here.
