* Wiki stats, such as the total number of pages, total number of links, most linked to pages, etc, etc.
* wiki info page, giving the ikiwiki version etc
* would it be useful to reimplement the hyperestradier search integration as a plugin?
-* Maybe it would be possible to make RecentChanges a regular wiki page, by making it a page that renders statically, but somehow runs the cgi at view time to dyamically render the changes? Then this could be a plugin too. How would this be accomplished in html though? Only way I know is via server side includes..
+* Support [[RecentChanges]] as a regular page containing a plugin that updates each time there is a change, and statically builds the recent changes list. (Would this be too expensive? There might be other ways to do it as a plugin, like making all links to RecentChanges link to the cgi and have the cgi render it on demand.)

Another, separate plugin system that already (mostly) exists in ikiwiki is the RCS backend, which allows writing modules to drive other RCS systems than subversion.
