You are currently using terms such as page, news, and labels to describe the sections of the Confluence software. The terminology fits but is not what is most widely accepted on the internet. It would be nice if there were variables for all of these terms that could be changed in one configuartion file. That way a user could use wiki, blog, and tags if they prefer. (Or favorites and colors )

It would only require the change of the velocity pages but would add a lot of flexibility and allow for easier theme creation and maintenence.
