No it’s not available yet though you could join in the fun by installing the latest SVN revision.

So why mention it?

Simply because a couple of articles back I opened up a new section for admin themes. At the moment it only contains my own but I think that is about to change. Textpattern 4.0.9 will come complete with a built-in admin theming facility so you will be able to try out existing themes with a simple flick of a drop-down box, not to mention creating your own.

Alongside that, as if it weren’t enough, numerous UI tags have been added to the admin page templates to make it a lot easier for plug-ins to add, subtract or move fields to their heart’s content.

So if you have the patience by all means wait for the official release. If you don’t then go grab the SVN.
