I’ve been using Arnaud Froment’s Extended Live Archives for a little while now and his latest .10 version is simply great. The majority of the bells and whistles are behind the scenes, but it does simplify things a great deal for the WordPress blogger. Extended Live Archives is very clean and delivers a sharp looking gateway to my (albeit small) archives.
Speaking of sliced bread. WordPress 1.6 Alpha got a nice bump with custom Kubrick headers from Andy Skelton.
