Just on the topic of redundancy -- in my experience designing UI/UX, it's not always a good thing to remove it. There's a difference between where something should logically be found, and giving people access to the most frequently used tools.
The removal of the ribbon, in my view, is a big mistake. While a lot of things are tucked away logically, it takes more time/clicks to do certain tasks (the grid is a great example). I've seen this most often when engineering is the focus of the UI, versus productivity. Simplicity is good, but reduction is bad.
I think we'll see more of this conversation at C3 gets more popular. Logic in UI is good for learning, but redundancy is good for productivity. I know the UI/UX is the reason I'm still in C2, despite the features.
Voice of one, but I'd heavily suggest including a ribbon that's either based on the most used tools (C2 is a great start) or even customizable.
