Blogger Feature: Abandoned Posts Functionality

Sometimes I start a post and decide never to finish it. Often, because I have discovered some flaw in my reasoning. Still, I hate to discard anything I have taken the time to write--as with saving all email messages, you just never know which thing you may want for some reason in the future. My work-around in Blogger is to assign such un-published items to an "Abandoned" category. But that will cause them to still accumulate and get in the way when reviewing the backlog of un-published posts (I tend to have a lot of those). I would like to see built-in system functionality for hiding posts in the "Abandoned" category.
