+The [[plugins/calendar]] plugin could use plugin data storage to record
+which pages have a calendar for the current time. Then ensure they are
+rebuilt at least once a day. Currently, it needs a cron job to rebuild
+the *whole* wiki every day; with this enhancement, the cron job would only
+rebuild the few pages that really need it.
