We made a couple of improvements to how priorities are shown for tickets in TopLeft.

In the old TopLeft Kanban boards, priority was shown as the color of the left border of the card. In the new UI it was shown as a label on the card, but some customers liked the way the old UI showed priorities. So we've added an option to show priority like the old boards.

To use this variation, edit a view and set the "priority display" option to Border.

The second improvement is for Autotask only. In the new boards you can now customize the color of priorities in the TopLeft settings section, and the color is used for the label or border in the board view.

Autotask users may want to customize priority colors because the Autotask priority API doesn't include the color.
