Whether a Kanban board has already been created for a project is indicated by the board icon to the right of the project name. Additionally you will find the board symbol within the detail view of projects in Daylite, shown at integrations.
If the symbol is colored, a board has already been created for this project. If the symbol is gray, no board has been created for the selected project yet. A click on the symbol takes you directly to the area of the project in Daylite where to create a board.
