When I moved "Via Positiva":http://www.viapositiva.net and its associated blogs from "TypePad":http://www.typepad.com to a custom installation of Movable Type, the ability to customize was one of the big selling points. The only annoying bit has been the lack of TypePad's swanky TypeList feature. It let you collect bundles of links, or Amazon URLs, or RSS feeds, and stick them in the sidebar without hacking the HTML code.

Enter "MT-Outliner":http://mt-plugins.org/archives/entry/outliner.php -- an awesome Movable Type plugin by Chad Everett. Stick all your links into a standard OPML file, and MT-Outliner can render them into a cleanly formatted link list anywhere on your blog. I already had quite a few links an a convenient OPML file, and the new set of links to the right of this entry shows the results. I have to say... I'm really, really impressed with Movable Type and the functionality that it supports when paired with community-developed extensions.

It's cool. No question about it.

Update: I've also added "RandomLine":http://mt-plugins.org/archives/entry/randomline.php to randomize the blog's tagline every time I post a new entry. In addition, I figured out how to tie MT-Outliner to the Movable Type administration interface. No more FTPing my links! The customization continues...
