The developer documentation is generated from the code, but it is possible to freely add documents as well. It would only contain information about how features actually work in the game wright now, because it's a coding reference.
I am not sure if discussing planned features in the wiki will help us much. At the moment, things are already being discussed in 3 places:
- Launchpad bugs
- Launchpad Blueprints
- The Forum
Keeping topics in a 4th discussion platform interlinked will mean more work for me.
It would be much easier to handle if we simply create a new bug once we have finished discussing what a feature should look like. That strategy has served us well during the last release cycle.
Having a separate forum thread per feature would also make things easier to find. I have yet to find out how to split topics in pyBB, if the feature exists at all.
