Just a suggestion for the blog app.
Could extra functionality be added to the authors part of the blog that allows authors to be added via the blog app instead of having to make them a user in the CMS?
I've had a couple of clients recently who have one website manager (they upload all the content, mainly blog content) but there are many different authors of the blog posts. Each time they want a new author added it becomes quite time consuming creating a user account, logging in, saving a blog post as that person and then editing their author profile, then deleting that user again. It's particularly time consuming with Paranoid mode is switched on.
Would really love to see this added.
