Suggestion Box?

Hi. I'm a new android user having fun with my Galaxy Nexus. I love the flexibility that Android provides to the user, I love Google's products in general and their vision, and want to see Android really succeed. As I actually have started to use it every day, though, there are definitely things that are a little strange that could use improvement.

I've been looking around to see if there's any kind of "suggestion box" section of the forum for floating ideas of how to improve android in the future.

It seems like users could brainstorm and swap experiences, ideas could gain support and it could help developers know where to focus. Maybe this already exists and I haven't found it?
