Todos and notes to a certain post

It's nice that we can communicate about a post.
I would like to see that extended by two features:

• ToDos: Maybe a team has to do stuff to complete a post: "Add a image", "add text", "check hashtags" and so on. Would be lovely if simple todos could be added, maybe even with a person tag, to see who is responsible for that todo. (Bonus: overview of my todos)
• Notes: Sometimes I would like to add some informations to a post, which should not be posted (and which is not really a chat) but gives additional information for the post to the team.
