I'm a user like you, this is a user forum, not the place to vent about everything you don't like in the new UI. Just had to read through all your mails....
There is a way to get customized workspaces back: Preferences, 4th option 'Enable....'. I never work in the 'newbie' mode which I dislike maybe more than you. You'll be able to make panels floating (not minimize to an icon, which I regret again), to create custom workspaces etc. What is not possible is to drag those fixed bars on top and make them floating. Agree about that, but my begging and pleading at least has got the ability for custom workspaces back. Please, instead of writing all those posts, introduce bug reports and feature requests like I'm doing all the time. And yes, I did post a request for rulers and guides for each version since CP4.
