Sometimes I think a MF is used by another MF, but somewhere (deep) down. For Example, “MF A” uses “MF B” and “MF B” uses “MF C”. Then I’d like to see the relationship between "MF A” and “MF C” and see that “MF A” → “MF B” → “MF C”. This would help me a lot with understanding new apps.
The Idea could also be generalized to Documents in general, not just MF's
