In reply to Matt.

I'm a long time solo publisher and I've never taken on clients. I don't fall into either of your groups of users. But, I think the edit features a user needs will depend on what the site is and how it is used. Also, what theme is used. I really think the most useful thing for WP to do would be a drag and drop which lets users pick their own most used options and keep them where they can get to them. Why does anyone need a page builder to add layout and content editing features to WordPress? All the features should be there, whether they get used often or just once in awhile. Each user has different needs but most of us like to dip into the kitchen sink and see what all those shiny buttons do. (I like having shiny buttons rather than hand writing the code myself).
