With this rev., the resequencing feature (with drag and drop) that was already available in list views is now available also in kanban views having a field with widget="handle". This works for main as well as x2many kanban views. Some code handling the resequencing has been moved from the list components (controller and renderer) to the basic ones, so that the logic is shared between list and kanban.
