First of all, thank you for the kind words.
Secondly, your points about lack of documentation and difficulty installing have now been addressed in version 0.3 to allow for a universal package that installs onto Joomla! versions 1.5, 1.6, 1.7 and 2.5 all from the same zip archive without the need for unzipping first. Obviously this might not be of much help to you now, but for anyone in the future this has been changed.
Thank you for your feedback and I hope that the new universal zip archive installs easier for you and future users.
