Can I track extra details on a conversation, like the publication I used?

Yes. Open Preferences → Conversation Fields, or tap Add Custom Fields on the conversation form, and add a field such as Publication. Field names can be up to 14 characters. Every field appears on the form for conversations and Not at Home visits; leave it empty when it doesn't apply. Saved values show on that visit in the contact's history. When you tap a field, values you've entered in it before appear as suggestions, most used first, and narrow as you type; tap one to fill it in. Below each field, Earlier visits lists what you entered there on that contact's previous visits, such as publications or videos you already shared, so you can choose something new. You can rename and reorder fields any time without losing what you entered. Archiving a field hides it but keeps its values. Delete it from the Archived list to remove the field and its values from every conversation for good. Fields and values stay on your device, are included in backups, and sync between your devices when sync is on; update WitnessWork on each device to see them there. They aren't included when you share a contact. Contact fields are managed separately in Preferences → Contact Fields. With data protection mode on, don't record religion, health, family situation, language, or ethnicity. If a field is missing from the form, check whether it was archived. For anything else, contact support from the Help Center and leave out names, addresses, and notes.
