Ledger
Every open item from every call, in one list.
The ledger is a note in Dana's notes app, rebuilt from scratch on every run from the routing records. It is grouped by client, tagged with owner, due date and whether the item blocks other work, and annotated with what the mailbox showed. Tick things off in the note; they stay ticked when it is rebuilt.
Sample ledger. Ticks live in this tab only.
