I really like the new Community design and I think that splitting discussion by product is a fantastic way to direct users.
I would like one more page, that functions similarly to the designer/server/promote pages, which have links to discussion, knowledge base, and ideas.
Ideally, this page would have a link/button that would bring you to each of the ideas pages for the various products, so eg:
User clicks a "Idea Center" link.
Here there are 5 links:
Community Ideas
Connect Ideas
Designer Ideas
Server Ideas
Promote Ideas
Each of these links is basically identical to the ones that already exist today (maybe the icon changes to be a lightbulb and the image for that particular product?)
That way it is easy to navigate specifically to suggestions, which I think will be helpful for ease of access.
