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, turn the cards sorting toggle on and choose Sort by priority.

You may also choose the order: descending or ascending.
