I think it would be really interesting and valuable to have the ability to select a specific field (dimension or measure) and have all "associated" fields highlighted, which would help to show which other fields may be impacted by a change on one field.
Associated fields might be defined as having other fields within it's own calculation, where a change in one impacts a change in another.
Even better might be able to have a diagram of all "interconnected" fields, those fields that are used "within" one another in functions and calculations.
