I'll let you know once we have mocks available publicly. Right now it's all in "draft" state.
How the community can help with the visuals? That's a great questions. We haven't really established any processes just yet. Right now, we're working internally on Design System. Until we have that, probably the best way to help is suggest ideas and improvements either here, OR on #meta, OR as github issues. Once we have Design System, some guidelines and processes established, it would be much easier to "collaborate" on visual side.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
