How can I sort cards in list by priority?
You can set priority to every card that you create. Priorities vary from low to critical.
Cards in a particular list can be automatically sorted by priority for you to see the most important cards always on top of the list. Kanbanchi will sort them automatically, without any drag-and-dropping and reordering on your side.
To activate Sorting by priority for a list, go to list settings and tick the box Sort cards by priority.
