Expandable project view INSIDE the project?

I just got the new OmniFocus 3, and as I understand that they want to reuse as many views as possible, the expandable project view doesn’t make any sense when I am already inside the project:

It takes so much space until I can finally see my ToDos. Also, why can I collapse the project here?

The UI is otherwise really nice, but this thing makes it feel cluttered and not very well thought through.
