You can customise the order in which Queues show on the Dispatch Board online, in the top 'Queues' container, and in the Queues tab.
To set a custom order, in the Queues tab, click the sort-order button in the top-right, then 'Set Custom Order'.
Click and hold the grab bar next to a queue, and drag up or down to reorder. Once done, click 'Save' to update the order of Queues as shown in the top container & Queues tab.
Note that this custom order is saved per user, so everyone in the business can customise the order in which Queues show, to suit their role and preferences.
