If we load some pages into a collection, e.g. by going to [[b:Cryptography]] and adding the following chapters
:[[b:Cryptography/Introduction]]
:[[b:Cryptography/History]]
and then go to [[Special:Book]], there is no option to change the text which will be displayed as the title of each page.

The user first needs to save the collection and the go to its page to add the alternative names, like
:[[b:Cryptography/Introduction|Introduction to Cryptography]]
:[[b:Cryptography/History|History of Cryptography]]

The extension should provide the user the option to execute this renaming through [[special:book]]. It could be used the same kind of [Rename] link which is available for items created by the "Create chapter" button
