Have you noticed any changes to the 'Posting' page when writing your blog posts?
They have moved the preview button.
Was happy with that no problems.
Was even more happier when I realised that they have fine tuned the preview altogether.
It is amazing, when you view preview now, you actually get a preview of your blog page, you can actually get to see what it will look like when published, no more small box showing you an approximate idea, this is an actually post on your blog with 'preview' written across it.
So way much better.
So the next time you are sat writing a post, preview it and see what happens. It will make getting your layout exactly how you want it from now on
