I think the hierarchy feature needs to expand. Only seeing one level below isn't enough. For example my structure is Big Rocks, Ideas, with Capabilities and Experiments being at the same level under ideas.
I really need to be able Group by Big Rocks, then Group by ideas to show the full structure on a board view. I should be able to accordion levels up and down when needed. Right now leadership can't see the details they want without going to 10 different boards and they have a hard time find a place when they go to a new board.
