The ability for users without any experience in using Data Modelling tools or those who are not computer savvy at all can have their ideas about how things should be modeled validated by real experts from within our team! We were looking into ways of validating user-defined conceptual models before implementation and this was one way that came up as being very useful. This functionality has enabled us move much more quickly through modelling projects than we previously could if there weren't expert people around helping validate concepts early stage - it's been really helpful so far.
