Idea: Categories support in address book / carddav

[robertmx]

Dear Devs,

thank you for your work on groupoffice. A lot of CardDAV frontends (thunderbird CardBook, DavX5) manage their groups by using the CATEGORIES field of the VCARD standard. It would be nice if that field could be used inside the contacts app of GO as well. The current group feature seems to be implemented as a list, containing all Contacts, disjointed from the VCARD representation. In contrast by using the CATEGORIES field, the groups could be dynamically discovered from the contacts by grouping over the CATEGORIES field. That would prevent the group information being lost by imports/exports and would enable seamless interoperability with the aforementioned clients.

cheers Robert
