Looks very nice the new interface and I hope that the functionality be great.
I totally agree with you. Yootheme forgot ZOO for much time, in this moment need a totally reborn. I love the way of ZOO constructs the content and their apps, but one more time, the core is very outdated now.
Nice to know about your work! Impatient for try a beta ;) !
Big hug Miljan!
