The most important part was given the least amount of screen time: How layout elements influence each other.
It is one thing to have elements stuck to a corner and another completely to have one box push down another. As long as they do not include a layout solver I am skeptical about the usefulness of their implementation.
Lets wait and see!

You can see that they have basic Flexbox-like layout support. There’s one shot of box resized pushing another box. I was analysing the video frame by frame, and found this:
Important bit is that “Flow: None” and padding. I think they will keep everything very simple, just making Vertical and Horizontal flows.
