I starting writing a blog this last week and I've constantly been saying to myself, "I'd like to just focus on what I'm doing"... Making the screen 1 column kind of helped but made the editor too big and I still got a glimpse of the meta fields below. This is the first I've herd of this being implemented and I think it's something that Defoe fly should be considered, without a doubt. It's just up to WordPress and us to make sure it's implemented in the most beneficial way. Looking forward to testing :)
