Yes, it would be certainly better to have the fully spelled title of the 
page. As you noticed, this page is now automatically updated, thanks to 
the indexmenu plugin (just add new pages, and they appear automatically 
in the menu).

I should be able to read the page title and substitute it in the list, 
but it requires to hack the indexmenu plugin. I will not do that soon, 
but I put an item in the todo list.
