I think there needs to be a site roadmap to check the state new of new features coming as well as when we can expect to see it.
This is an example of unitys roadmap - https://unity3d.com/unity/roadmap
This will help us with submiting new ideas - we won't submit an idea thats on the roadmap.
Maybe have an idea colunm with a linked lab idea.
@Ianmorlord has told me you already have a roadmap then why not link it to the website?
