To me it has to be both functional and simple. I think that users enjoy the 2.0 stuff like bigger text and cleaner layouts.
EXACTLY my thoughts!
It is difficult to compare with modx. I like ExpressionEngine although they are mostly geared to blogs their interface is simple and easy to understand.
No matter if blog or not, the principle stays the same -> Manage some kind of content (erm, ressources

) Unfortunately I can’t find a standard view of the control panel... On the demo there is only a not so stylish one available. Could you perhaps take a screenshot of the default panel and the publishing area? Thanks!
What would be interesting to have in modx would be 2 UIs, a developers UI and a contributers UI (I guess this can be easily done with contexts).
Again: EXACTLY my thoughts! My intention is to create an UI for the common user, that usually is a publisher. But the principle is the same for all users: Keep it simple and intuitive!
This would eliminate the need that some folks have to create simple front-end authoring.
Well, I think that doesn`t exclude each other. The frontend editing is also a point to discuss (and to improve, QE is cool but also old, e.g. I think MODx could raise the bar with some kind of inline editing...).
This would be very cool to have out-of-the-box and help bridge the gap between contributors and developers *the current UI is very cool but it over the top for simple authoring - both 09x and Revo). I used a project manager tool that had a client view and a contributor view and this was very cool since it simplified things for the client. Is this doable or a good idea?
I’m with you... Could you share some screenshots of this tool (both views)?
