Request that when a Measure is selected, all the fields that are called or referenced within that measure be Highlighted.
Recently ran into a situation where a longstanding report utilizing nearly 100 different measures and around 7 different tables needed to be cleaned up. It was a massive effort to lookup and track which columns on those tables were actually in use and which were excess.
I believe this change would work just like visuals do when they are selected and the fields being used get highlighted.
a possible bonus might be to color code the highlights ex:
yellow font indicates the selected object uses the field, and a turquoise font indicates the selected object is used by the field.
