From forum post:

In a Java IDE, like IntelliJ, I can look at a base class method and ask which classes override this method.

In QB2, I cannot easily find out which configurations override a step higher in the configuration tree. It would be very handy if I am looking at a step defined in root and obtain a list of all configurations that override it. That way, if I have to change the root step version, I may need to change each configuration that overrides that step so I need to find them easily.
