It's been a while since I looked at Gutenberg so I just installed the current plugin version (0.10.0) and gave it ago.

After a few minutes of typing and rearranging blocks, I was not sure if the post was already saved automatically and tried to manually save it. I couldn't find the "Save Draft" button so I first clicked on "Revisions" because I thought maybe there's a new revision. However, that unexpectedly took me to the actual revisions screen.

After going back, it took me a few seconds until I found the "Save" link in the upper left of the screen. Usually in the WordPress admin, there's only a page title in the upper left. I guess that's why I didn't think of looking at that area of the screen.

I think I'm not the only one who encountered this. Perhaps it's something that should be included in a few more user tests.

A few ideas to improve this:

• Move "Save" link somewhere else, e.g. to the right side of the screen or perhaps even combine it with the "Publish" button
• Improve visual indication when a post is saved, e.g. by making the message green.
• Add autosave functionality, again with a clear visual indication that the post was saved (periodically). In the current editor, such a thing exists below the textarea (inside <td class="autosave-info">).
