* 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..
* etc
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.
* *parsers* and *formatters* are basically what I've been calling [[PluggableRenderers]]. MoinMoin separates these, so that a page is parsed to (presumbly) some intermediate form before being output as html or some other form. That's a nice separation, but what to do about things like markdown that are both a parser and a formatter?
* *macros* and *processors* are analagous to preprocessor directives. A processor can operate on a large block of text though.
* *themes* should be irrellevant (ikiwiki has [[templates]]).
