Edit and preview a blog post without hiding (draft)
It's amazing to me that this issue hasn't come up yet for me (probably as most clients simply draft/preview a blog post BEFORE publishing, never after) - but is there any way of enabling blogs to function like regions, i.e. "Save as Draft" so that changes can be previewed only by a CMS user, BUT keep the previously published blog (pre-draft) available on the live site.
The problem my client has, is that when they want to edit a blog, they swap it to draft (to preview changes), but a drafted blog means it's hidden from the live site. Maybe this isn't possible - but could it be?
Any help would be great!
