The ability to edit all pages without switching between plugins. I like how easy it was when editing layouts with different page types (blog posts, galleries). Sometimes you have multiple elements from one layout in your sidebar so if they don't match up perfectly then sometimes things look wonky but this could be because there's too much going on or something else entirely - not necessarily cms related though. It also makes adding new pages really quick. As time goes by we're realizing more needs are being met through custom development instead of using pre-made templates/plugins which would save us lots of trouble down the line.
