Hi Ben,
What you may like is to browse multiple parallel hierarchies.
This is done in TaxoNote:

AFAIK it was never done in any Smalltalk flavor.
Cheers,

Working on case 12498 [1] has evolved to the idea of the class-side hierarchy showing meta-classes per attached snapshot. ��I'd like some community feedback on the idea. ��Note the metaclasses are bolded similar to how bold indicates class-side methods.

Thanks Nicolai for your help so far.
cheers -ben
