Need 'Save as Draft' next to 'Publish Story'

As most of you know, delivering quality articles might take days or even weeks of work, meaning you gonna deal with lots of work in your Drafts.

The problem is: I cant find 'Save as draft' button anywhere. Yes, the content get's saved once I edit something and close it without hitting 'Publish story' and I can find it under Drafts section on Blog dashboard. Tho, closing articles this way makes me feel very insecure as content might not be saved at some point and I could lost all my work.

Manually hitting 'Save as draft' button, getting a nice pop-up notification 'Your draft has been successfully saved' and redirecting to the URL user has been previously, would be a nice way of doing this.
