This is the weekly Hackers Highlight, showcasing various interesting information that happened in the last week of WordPress hacker’s mailing list, wp-hackers.
Chris Jean questioned whether it’s possible to hide the parent of a child theme in the Manage Themes dashboard area. While this is potentially useful to avoid user confusion (so that they don’t activate the parent theme when they should be activating the child one), I don’t think this is a particularly necessary issue. Users might not even understand what a parent/child theme is: just tell them precisely what theme to activate, and that’s it.
Joost de Valk offered a small fix so that /wp-includes/link-template.php uses less database query. Nice catch.
Ptah Dunbar asked whether there’s a WordPress UI guidelines somewhere. Apparently there is one, except that it’s written in German. Anyone interested to do an English version?
Mike Schinkel found out that WordPress always run a query for posts regardless of whether you need it or not (say, if you’re using a custom query). The discussion that follows talked about ways to disable the query_posts() function.
