Personally, I’d really prefer being able to have the admin pages look and behave the same as they did in 2.3.3. That version worked just fine. (ok the ‘visual’ editor was crap, but I never cared for WYSIWYG when editing html anyway, I’d rather just type the html that I need myself and be done with it)
The new admin layout frankly blows chunks. I’ll never understand why people have to change things that work just fine. At the very least there should be an option to use 2.3.3 look & feel if it’s preferred and in my case it most definitely is.
