Creating a new task
Use "Add new task" button to add an item to the board. The task creating form will appear. The fields for displaying on this form you can define in “Cards Setup” -> “Form” section of Kanban board.
Another ability to add task very quickly is the button on swimlane.
Click “add” button and type task name. The task will be placed in the task and row where you clicked “Add” button. You can edit this task fields later from standard Kanban task edit form.
