If we click on a feature Inventor should highlight dependent Features with different colors in browser. This will be helpful in tracing the model history and modifying the parts.
For Example in Below image:
I clicked on Extrusion1, then Parents highlighted by Green color and Children highlighted by Blue.

May be this can be extended in iam files as well to highlight the Parts which are constrained to each other.
