I'm wanting a [[map]] (with indentation levels) showing page _titles_
instead of page 'names'.  As far as I can see, this is not an option with
existing plugins - I can get a list of pages using [[inline]] and
appropriate [[wikitemplates]], but that has no indentation and therefore
doesn't show structure well.

The quick way is to modify the map plugin to have a 'titles' option.  The
hard way is to modify inline to have an indentation option, in which case
inline will be a superset of map functionality.  The second option seems a
little wrong from the point of view of perversely extending what 'inline'
means, but it seems right from the point of view of combining common
features.  Maybe adding template support to map is a more useful approach
than just adding a title option.

Thoughts, anyone?  --[[KarlMW]]

We'd also very much like to have an option to display the title of the page instead of the filename in the map plugin. --Andrew

There's a patch implementing this in [[!debbug 484510]]. It needs a few fixes
before I merge it. Now applied. --[[Joey]]

I noticed that when the pagespec returns no map items, the map plugin does not close off the ul and div tags. Below is a simple patch 
that seems to work on the examples I tried. I am a beginner so please help me out here. Thanks. --[[harishcm]]
