This is now slated for Couch v1.4.5, which will follow shortly after v1.4. Full mockups should be complete in 2 weeks. I am very eager to get some community feedback and bug reporting on this once we have a candidate release available. Also, once v1.4.5 is ready I am sure many of the admin panel feature requests will be addressed shortly after. I hope people will be pleased with the end result; it is an intimidating task to create something that will be used and scrutinized by designers.
Looking forward to seeing the new look for Couch - we all need a bit of a makeover now and again. An interesting article on feedback here : http://sixrevisions.com/project-management/feedback-the-creativity-killer/ Those sites I've worked on and consider a failure, or at least not as good as they could have been, are those where I've been subjected to a committee of clients (usually all in disagreement as to what they want). My rule now is 'no committees' - just one decision maker. I'm sure the Couch community will give feedback of the helpful and constructive sort, rather than 'this is my opinion on the appearance'!
What is happening in v.1.4?
