I'd like to see some way to include certain files from the underlay only when the wiki has certain plugins enabled. For example:
* Only include smileys.mdwn and the smileys subdirectory if you enable the [[plugins/smiley]] plugin.
-* Only include openid.mdwn if you enable the [[plugins/openid]] plugin.
+* Exclude openid.mdwn if you disable the [[plugins/openid]] plugin.
* Include shortcuts.mdwn only if you enable the [[plugins/shortcut]] plugin.
* Include blog.mdwn only if you don't disable the [[plugins/inline]] plugin.
* Include favicon.ico only if you enable the [[plugins/favicon]] plugin.
