Boards
A board holds columns. New boards start with three columns: To do, Doing and Done. Rename or add columns from the board menu.
Cards
Press n to add a card to the focused column, m to move it and x to close it. Every card has one owner.
Backups
All data lives in one file. Copy it while the server runs; writes are atomic.
cp /var/lib/taskflow/board.db /backup/board-$(date +%F).db
