Measures that reference and depend on other measures can be difficult to trace and debug. To make this easier, provide the option in the field list to show the measures that are referenced by other measures. This should be optional and performed individually for each measure to avoid unnecessary performance overhead. Here's a conceptual mockup:
Excellent idea, and something is definitely needed. I'd rather see something visually though that looked like the Power Query Dependencies view vs an outline where measures are repeated depending on their predecessors.
But anything is better than what we have now, which is nada.
