there should really be like sub categories. for example, you click on suggestions, takes you to another page with links like [Mod suggestions] [Website suggestions] [game suggestions] etc
Edit: Examples added
Reminds me of something I posted once on tagging threads.
Perhaps you could add an examples section like I did here
I support your idea by the way. It would really help with navigation of the forums and organizing posts a bit closer in terms of topic than how the categories are currently.
