I find the process of adding collaborators to a card very confusing, and not very helpful (for us at least). It doesn’t make sense to me that I have to somehow (I forget how every time) add a collaborator in order to make a comment on a draft card that’s directed to someone. Why can’t it just add that person as a collaborator (if that’s actually required) when I add a comment directed to them? Also, the fact that if I publish a draft, it clears all my comments also doesn’t make sense to me. I want the team to be able to see the content and use it, even if the content isn’t “complete”. It seems to me that it doesn’t really mimic the real world where I’d just want to publish something, with intact comments directed at people, and then adjust it as I get their feedback. Going someplace else to manage drafts seems like an unnecessary extra step that actually hinders collaboration and feels very waterfall.  Perhaps there’s some feature functionality that this was intended to support that I’m just not grasping though.
