Some users, mostly when reading an existing document, tend do disable the view of comments with View → Comments. The problem with this option is that comments disappear *completely*, which increase the risk of deleting a note by accident. There is an extension(1) that maintain the comment's anchor visible even when "See Comments" is disabled.
The problem with the use of this extension is that those anchors are completely passive: other than deleting, you cannot do anything with them and to see the comment content, you need to enable "view comments again. So I think there are two point that can be considered: 1- Set by default the option of viewing note anchors even when "view comments" is disabled. 2- Make note anchor show a tooltip with the note content, the same way footnote anchors show footnote content when hover over it, but of course only when "view comment" is disable. What do you think? Regards Ricardo (1) http://extensions.openoffice.org/project/NotesAnchor
