Showing Backdrop to my client, one of her reactions was "Oh nice, it already has Drafts built in. So how do I share my drafts with the rest of my group before I publish?" So what she's looking for isn't really Backdrop's idea of "draft", which is just "unpublished" by another name, yes?
I haven't seen any modules ported over or discussions about this general topic. Is some kind of editorial workflow not something that people have seen as a need? Or are people handling this in custom ways? Just curious what your thoughts are.
