Like others in this thread, I tried using this some years ago. But unfortunately the friction of yet another specialized tool kept me from actively maintaining it, which of course makes it entirely worthless.

I've started just using Google Contacts for this. It syncs and integrates with all my devices, supports birthday reminders, relations and custom fields, and has a general purpose note taking area for gifts and other details.

I only wish the custom fields were more powerful/versatile and that the relations could be hyperlinked with other contacts instead of being just text fields.
