Better visualization of Initiative hierarchy and initiative-to-feature grouping

I would like to be able to see a hierarchical lists of initiatives to see how they are nested based on the 'rollup' relationships. The rollup capability is useful but it's very hard to "see" it once a bunch of things are linked.

This would be especially valuable to consumers of the notebooks and roadmap views, because those folks (sales, marketing, execs, etc) are probably less familiar with all the details in Aha compared to the Product Managers who work with the content daily. I "know" what the initiative roll-up relationships are (most of them), but it's not obvious anywhere I look in the various screens.

That relationship info communicates a lot on it's own, and would be good to surface it more explicitly, with some interactivity.
