And most tools were tailored towards that use case! The (open source) exception that I remember from back in the day was Green UML. Their sourceforge is still live and saying "green is a LIVE round-tripping editor, meaning that it supports both software engineering and reverse engineering." Renaming a method in a reverse engineered UML diagram and seeing that reflected in code was pretty neat. I never got why this isn't a standard feature until now. Hearing about the relationship between UML and broken project management I get it (I wasn't into that at that time, except that I never bought into the waterfall promise). Let's hope someone will revive UML as a code navigation and round trip refactoring tool. That would help a lot and nicely fit an agile approach.
