Plugin can be enabled at the site context but not configured

Disclaimer: this might not be a bug.

The Text Editor Extras plugin can be installed and enabled in the Admin -> Site Settings area but the "settings" link never appears afterwards.

This seems to suggest that this may be by design:

You can actually enable the plugin via the checkbox. I don't see the getEnabled method overridden anywhere so I'm not entirely sure what's preventing the settings to appear.

We occasionally get requests from clients to be able to add HTML code to the "About this Site" text field in the Site Settings area and being able to use this plugin for that would be quite nice.
