I'd love to have a "Draft Author" permission level that would allow folks to create & edit cards, but not publish them until they are reviewed by an expert. For those of you familiar with Git, it would allow for a similar workflow to submitting a pull request.
New user permission just for drafting Cards, not publishing

Hi everyone
Great news - in our latest product update, you’ll see we’re announcing the ability to manage publishing rights at the Group level in a Collection, meaning you can make a Group of users “draft authors” if you’d like. 
I’ll close out this post now!
