Sleek revamped UI?
Until the UIs across all CS products are consistent, the UI as a whole is a complete failure.
It is astounding how after all these years, the CS products STILL have different UIs and UXs. Even the way the user accesses basic functions for layers (rename, duplicate, etc.) are not consistent from one app to the next.
So please hold the comments about the UI, other than "We realize we have completely failed, and our different product groups do not care at all about a unified experience across the suite, and each just want to do their own thing. And nobody in Adobe was willing to beat our groups up to force them to have some consistency. That is priority #1 for our next release."
