[Cuis-dev] [Preference] Category as domain name

[Luciano Notarfrancesco]

Interesting. I will think more about this before giving an opinion about
your proposal. But in the meantime I wonder, what if every package had a
dictionary of preferences? Would that work with the way you arranged your
code in your packages? I think this could also address some of Gerald’s
concerns regarding modularity.
