+struggle due to the important amount of tasks to fulfill. Those task are
+already complex enough. Having to remember them all and follow up on
+them can be a real burden. Luckily, Odoo enables you to efficiently
+visualize and organize the different tasks you have to cope with.

+--------------------------------------------------
+
+Once you created several tasks, they can be managed and followed up
+thanks to the Kanban view.

+The Kanban view is a post-it like view, divided in different stages. It
+enables you to have a clear view on the stages your tasks are in and
+which one have the higher priorities.

+The Kanban view is the default view when accessing a project, but if you
+are on another view, you can go back to it any time by clicking the

+Sort tasks by priority
+~~~~~~~~~~~~~~~~~~~~~~
+
+On each one of your columns, you have the ability to sort your tasks by
+priority. Tasks with a higher priority will be automatically moved to
+the top of the column. From the Kanban view, click on the star in the
+bottom left of a task to tag it as **high priority**. For the tasks that
+are not tagged, Odoo will automatically classify them according to their
+deadlines.
+
+Note that dates that passed their deadlines will appear in red (in the
+list view too) so you can easily follow up the progression of different
+tasks.
