Thank you for your enthusiasm and you have posted some great ideas. I would like to direct you to the previous news post though:
viewtopic.php?t=2483We currently are a very very small team and our current goal is to get a finalized 1.1 version out first. After than, there may be time for some of these other projects.
Question, have you ever considered making a mod yourself? The game is completely open source, we have tutorials on how to start mapping, and there is some tutorials floating around the net on how to make models for Q3 based games.
