In an interview on Nublue, a web design agency, EllisLab Chief Creative Officer, shared a tiny bit about ExpressionEngine 3:
Are there any elements of the design within EllisLab applications that you are particularly proud of and why?
Yes. However, those elements aren’t public yet, as they are part of ExpressionEngine 3. I came to EllisLab after ExpressionEngine 2 was released, so aside from some small tweaks here and there, ExpressionEngine 2 is largely not my work. In the curious case of ExpressionEngine 3 I’ve taken my time trying to sculpt a user experience that will feel at once both new, and familiar. From that base, I plan to iterate and improve the control panel even further.
