Yep, maybe I should update the situation of Code Completion Plugin. I'll start by saying that progress is really really slow. I haven't written a single line of code yet. This is mainly because the situation of the Wiki (the lack of information, some of the information is outdated).
In my book the Wiki is more important, especially now. The RC3 release coming closer and when it's released, it will atract a lot of new people to this project and then the documentation is very important. So when the Wiki is in that state that it can give new users good, up-to-date information I'll continue with the Code Completion plugin.
And, again, I'll remind everyone that this is open-source software. Anyone can start creating their code completion plugin today. Or if you don't want to create a new one, you can always submit patches to the old one.
