Minor Blog Tweaks

I've recently made a couple of minor tweaks to the blog:

• Category archives now display all the entries in a category rather than just the last 20 entries.
• The links and blogroll navigation on the left now uses a cascading menu rather than displaying a huge, long list.

The category display change was a 5 minute job but the blogroll menu took most of the afternoon to get it the way I wanted, and is accomplished totally within CSS; I've used no javascript at all to create it. I'd appreciate feedback over whether the new blogroll menu is preferable to the old style. I've noticed it's easier to navigate if you move off a section sideways before trying to open up a different section rather than trying to move straight down between the sections.
