How to add all cards to the Gantt chart automatically?
Kanbanchi default setting for all new boards is to choose cards you want to see on the Gantt chart when switching to this view. It helps to have only necessary cards on your timeline leaving all the cards that represent side tasks or contain descriptive information on kanban and list views.
However, if the nature of your project requires all cards to be on the Gantt chart, you can change your board setting to adding cards automatically. This option may be found in board settings.
If there’s a need to remove any card from the Gantt chart, board collaborators may do it in card panel.
You can have different settings for different boards for your convenience.
