It's time to take CMS content authoring to the next level. Users don't want the process of writing to feel like filling out a form, they want a clean white page, and the tools they need when they need them.
The example of Medium has proven that authors don't want to be distracted by clutter. While a filterable table with columns for name, timestamp, content type, author, published status and available actions, plus a bulk operations form may make sense for a site owner, an Author is concerned with her own content and it's status.
Removing the visual noise of tools that are not being used frees the mind to focus on the content, but removing the tools from constant view should not mean removing functionality or power.
A CMS needs to illuminate for the user what the underlying structure of the content is so that they can produce semantic, reusable content readable by humans and machines.
