Board views give users the opportunity to save their own views of boards as private or public.
Views will save filters sorting, types of view, orders of dimensions, and other specific settings.
The possible views are ones of : kanban (former list view), calendar, chat, Gantt chart and analytics.
All views are equipped with individual URL addresses so they can be shared with other collaborators.
It’s possible to enable or disable showing child cards and timeline inside a view.
