[site functionality] Ask to save edits before publishing

I'm a little hesitant to post because I'm new and because there's not much activity here, but I realised that in my newness I've messed up once or twice in the posting of a snap - I went to edit the automatically suggested title & description, filled in all the relevant categories/tribes/etc and hit publish - but forgot to hit save on the title before publishing. So I'd like to propose either asking something like "looks like you've started editing, save/discard changes?" or just automatically saving and then publishing without prompting. To help out noobs like me.
