Thanks Kardotim. Yes I'd looked there but didn't think what I had b4 was named 'Quick Drafts'. What I'd used had simply been a list of drafts but I don't recall its title.
So, have now tried selecting Quick Drafts and it does appear where previous version appeared, BUT that selection is NOT retained once I go out of Dashboard. That is, I have to open up Screen Options again to be able to see Quick Drafts!!!
I surmise previous option has been modified with new feature, 'What's on your mind?' for jotting new work and doesn't have room for my half dozen drafts. Yet if I select 'View all' then the screen changes to show ALL posts, not drafts.
So it really is no improvement whatsoever for I'm no better off - I might as well head straight for Posts/Drafts in the first place, ie. a lengthier process than available last week!!
There are obviously glitches in this and its not been quality assured b4 going live. Perhaps I could request an enhancement with subsequent QA?
