Recent changes has become rather crowded with all that cursed popularity
of Wikipedia :-)
One often-mentioned solution was the ability to filter Recent changes by
categories. Well, now you have it!
It's turned off by default, no worries. To enable, set
$wgAllowCategorizedRecentChanges
in LocalSettings.php
It uses my aforementioned class to determine wether an article belongs
to a category or one of its sub(subsubsub...)categories. Categories can
be entered on the Recent changes page, separated by "|". You can filter
for articles belonging or either any or all of the given categories
(OR/AND).
Once the usual authorities had a look at it, I'd like it to be enabeled
on some medium-sized wikipedia to determine the impact on the database
slave servers, which might or might not be severe.
I think this would be a very efficient way of managing our "RC patrol
forces" by dividing the huge amout of changes-to-be-checked into smaller
chunks.
What's missing is "articles that don't belong to any category". Yet!
