Manual:$wgAllowCategorizedRecentChanges

Details
Enable filtering of categories in Recentchanges.

From the mailing list tech-l:

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!

Compare applying Related Changes to a category: this seems to be the same as applying Recent Changes to it, except that the latter also shows changes in subcategories.
