How do I connect Todoist?

Go to Settings → Task apps → add/open the Todoist card → Settings, paste your Todoist API token, then press Connect. To get the token: open Todoist → Settings → Integrations → Developer tab → copy your API token. The token is sealed in your Mac's secure storage (Keychain); only the encrypted form is saved, the plain token is never written to disk, and the app can't read it back after saving. Disconnecting deletes it.
