When we want to access the full list of subpages of a given page we usually use [[Special:PrefixIndex]] ([1], [2], [3], [4]), but currently it always displays the fulltitle of the pages, which can make the list harder to understand. This is particularlly true when dealing with pages which are mostly structured as subpages of some other page, as currently happens on Wikibooks projects ([3], [4]), since we don't have a proper way to define what is "a book" (bug 15071)

It would be interesting to add a new field to the current form:

-- All pages---------------------------------------
| "Display pages with prefix: [_______________]   |
|                  Namespace: [___________] [GO]  |
|                                                 |
---------------------------------------------------

like this:

-- All pages---------------------------------------
|  Display pages with prefix: [_______________]   |
| Format titles hiding prefix [_______________]   | <-- New field -->
|                  Namespace: [___________] [GO]  |
|                                                 |
---------------------------------------------------

The content of the second field could be (by default) equals to that o the first field when the special page is acessed from a link like
[[Special:PrefixIndex/Test]]

One option would be to add a link which could call a jQuery function like this:

$('#mw-prefixindex-list-table td a').each(function(index) {
	$(this).text( $(this).text().replace($('#nsfrom').attr('value'), '') )
});

Compare the default list from for "Wikipedia:WikiProject Australia/"[5] with the list displayed after that JavaScript is executed.
