Right now though the plugin is added to my wordpress installation and it powers the newly created archives page. I used to have an archives page earlier while with Movable Type (no there wasn't a chart on it). I couldn't find a way in Wordpress to create the exact same thing so it was not part of the blog till now.
Having a full archives page means I can shorten the lengthy and ungainly list of monthly archives in the side bar. Some times with short posts the side bars is even 5 times longer in length than the content area (or it used to be that way till now)
Update May 22, 2014: This site isn't powered by Wordpress now, but the plugin mentioned about vaporized long before that
