Hierarchy view- Feature request

Hello all.
what if implementing browsing capabilities in hierachy view(HV). So one will be able to move back and worth on class hierachy.

Currently what am I doing as a workaround is
- open HV for ClassA (inherited from ClassB)
- selecting ClassB
- goto ClassB implementation
- open HV for ClassB
- ... and so on

Will be nice to build hierachy for ClassB, for instance on double cliking while browsing.

What do you think?

Regards.
Andrey.
