New hack CardsPlugin, created by psuter

Sorting cards in stacks


A new macro [[Cards(...)]] shows a whiteboard containing index cards organized in stacks. Adding new cards interactively by clicking a button, move cards by drag-and-drop and double-click cards for editing or deleting.

Cards are stored in a new table in the Trac database.


[[Cards(stack=todo|wip|done,label=To Do|Work in Progress|Done, width=800)]]

Known Limitations

  • There is no history or undo functionality.
  • There is no tracking of users. Everyone with CARDS_ADMIN permission can freely edit any card.
  • There is no support for collaborative editing. Changes only become visible when the page is manually refreshed. There is no conflict detection or resolution mechanism.


  • stack: |-separated list of stack names. (required)
  • label: |-separated list of stack labels shown instead of the stack names. (Defaults to the stack names.)
  • width: Width of the whiteboard. (Defaults to 400.)
