The project tracking tools I'm familiar with require that you keep a side tally of progress if you want any sort of useful historical graph. Each time you update the project plan, you take a separate set of notes, type them into a spreadsheet, then make a graph.
Screw that. I'm going to automate it. Unless it's easy to see the trend of progress against estimates (and the history of estimate changes as more is known about the problem), it's too difficult to learn to estimate better.
My last big project took a major hit because of lousy estimates.
Re:Check out Twiki & XP Plugin

I've actually been using an antecedant of XpTrackerPlugin. XpTrackerPlugin looks like a step in the right direction, though it still suffers from the "now" problem. You can see what the project/iteration looks like at any given moment, but to spot trends you need to record a lot of information on the side so that you can make your own graphs.
