Software Project Management: Retrospectiva

I must check out this application, it looks really reasonable.
Introduction

Update
Had some troubles installing retrospectiva on my ubuntu box. The solution was to do a:

rake rails:freeze:edge TAG=rel_1-2-3

...in the retrospectiva app directory.
The source of this problem was that i have installed the rails version:
rails-1.2.3.7116 which seems not work with current stable retrospectiva version, this incompatibility is sadly not detected by retrospectivas environment.rb because the check there checks only for the major and the minor version which was corectly in my case. Otherwise everything noted in retrospectivas Quick Install Guide worked like a charm.

Update 2
This tool is awesome. Love the changeset feature, the easy setup, ticket filter and more. Can't wait to hear what non-programmers say to this easy interface.
