usually are shown as links below a page. The ewiki-builtin EditThisPage,
BackLinks+ and PageInfo+ are ["action"] plugins for example.

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