I agree with TheWyrm that it's a problem that new feature suggestions get lost in the General forums. Good ideas get lost and people will feel less encouraged to share them. I also think this creates unnecessary duplicated posts and more work for the administrators. Just like most forums or ticket systems have bug reporting, they usually have a dedicated section for feature suggestions.
Like I mentioned earlier, I personally think a better solution would be a new forum for it, called Feature Suggestions or similar. There would be no voting, but you could estimate popularity by number of posts, and people would not have to register on a new site to post ideas.
I think it should be a forum for brainstorming C2:s short- and long-term future, so anything goes. Of course, it's just brainstorming, so there should be no obligation for official answers. The best official posts there would probably be estimates of how big an undertaking it would be, to help people adjust their expectations.
