This release was basically written by Simon Pritchard. I just added the finishing touches.
Fancy new style
Version 1.7 adds an integrated multi-level navigation UI to the archives, perfect for sites with a large number of posts.
See a live example.
New formatting tags
First, you have %category_link% and %category%, which will output a category list for each post.
Secondly, you have %date%, wich will print out the publish date of each post. There is an additional field where you can customize the date format.
If you like the new features, go thank Simon for his effort.
