Snippets/Multi-column sorted categories

Instead of an unreadable old-style, concatenated, unsorted, long list of categories you can now choose to display your page categories as a modern, multi-column, sorted table.

A really nice and readable layout for MediaWiki page categories. Very easy to implement.

Simple PHP patch
Patch valid for MediaWiki 1.27, or earlier. You only have to change 5 lines of code.

rcsdiff -u includes/skins/Skin.php

Small change in CSS
Edit .mw-normal-catlinks { column-count:6; }
