The thing about your CMS is who is going to be using it? I looked at it and it just seems overbearing for what I want to do, I mean look at all those buttons! And I'm a web developer so why would I want to use all of those buttons you have there, to me it just takes up space. Now for someone else who is looking into using this maybe they want to use all of those buttons, but usually a person who doesn't know much about a program and sees a lot of buttons will more than likely not stay either. What can you do you ask? Well you can combine all the form elements into one dropdown button. That'll clear up a lot of space for one, but just combine elements to drop down buttons and that'll make it a LOT cleaner and better looking.

I think you need to redo the interface a good bit before this is ready because I just don't feel like I have any power over the content. I would also recommend updating all the content at once like you suggested you were going to be doing.
