Comment 7 for bug 733778

The "zettelkasten" application also provides a nice example of a list widget.

If you look at the following screenshot of the running java .jar, you see the content of the opened note in the top left frame, surrounded by frames (with white borders) containing additional meta-data:
 * lists of tags assigned to the note
 * additional comments
 * list of citations

Then on the right you see its global navigation lists (zim has them on the left which makes more sence to me).
The currently opened tab lists all links contained in the notebook, but there is as well a tab that shows a table with all node titles with creation and modification dates, etc.

Now for zim I would imagine a such an additional list frame (probably shown above the note frame), to be under whatever context is selected by the left tree/list/tag frame (with tabs showing only items in the scope selected on the left).
