Use cases

  • Let users type new tags directly on a contact detail page
  • Quickly categorize a contact with new labels without a separate tag creation step
  • Import contacts with tags where the tags may not exist yet
If a tag with the same name already exists, it will be reused rather than creating a duplicate.
