Can I view my tickets as a Kanban board instead of a list?

Yes. Use the two view icons to the left of the "Tickets" title to switch between the list view and the Kanban view. Your choice is saved to your view settings. In Kanban view, the three-dot menu gains a "Configure view" option where you choose which field forms the columns and which forms the swimlanes; the defaults are Status for columns and Priority for swimlanes.
