Linking entries
Type[[ anywhere in an entry’s body and an autocomplete opens, searching entries across your folders by name. Pick one and the link is in place.
Links render as colored text: accent-colored when they point to an existing entry, dimmed when the target doesn’t exist (yet).
Many fields are links too — a task’s assignee points at a person, a person’s organization points at a company, a deal’s client points at an organization. Setting these fields connects the entries the same way a link in the body does.
