This wiki page is kind of a roadmap. What should go in there. Many things mentioned there are already in the 3.1 webapp/webconsole. So be sure to check ou the 3.1 starterskit
It seems like app on wiki have a few more features (for example admin has task reassignment), but app in 3.1 is good enough for me.
Correct, there are some small differences. Those still have to be implemented in the webapp in CVS
