Shared board: everyone with this link can view and edit it. Changes save automatically, and other people's edits appear here within a few seconds.
Each circle is a section. An arrow points from a section to the section it needs something from. Arrows appear automatically when a section is ticked under "Dependency (sections)" on an action. Pick a section below to show only its arrows.
Every action with a horizon or date, plotted against time. Items placed by horizon only (no date yet) show as a hollow marker in the middle of that band. Click a marker to jump to its card.
