[RCD] Extra contact details in address book, bounty?

I was disappointed to see that the feature request that most interests me (adding extra contact details to the address book http://trac.roundcube.net/ticket/1332930) got moved from 0.2beta to 0.5... which means it's a LONG way off. In order to encourage development (since I'm in no way, shape, or form a developer), would it be possible and/or appropriate to add a bounty for this feature? I don't have a ton of extra cash (my fiancee is in graduate school), but could offer $75 as incentive for someone on the list to put in the work.

If you prefer not to do this sort of thing please let me know.

Thanks,

Doug
