:README.fragments

fragments/blocks/*

Contains small include() scripts to be loaded into "yoursite.php"
as "sidebars" and the like for beatification purposes.
Oftens these are reduced but useful ["page"] or ["action"] plugins,
performing common tasks, like printing the list of newest pages or
some sort of menu, or even random page links.

You cannot modify the README.fragments file, but anyhow any ideas or suggestion should as usually get filed on BugReports, UserSuggestions or even better the README.fragments.Discussion.
