Designing Kanban views

We will improve the todo_stage module we have been working with to add the Kanban view to the to-do tasks.

For this, we will use a new data file, views/todo_kanban_view.xml. We need to edit the data key in the descriptor file, __manifest__.py, to append this new data file at the end of the list.

Next, we can create the actual XML file where our shiny new Kanban view will go, at todo_stage/views/todo_kanban_view.xml:

<?xml version="1.0"?> 
<odoo>

  <!-- Add Kanban view mode to the menu Action: -->   
  <record id="todo_app.action_todo_task"
          model="ir.actions.act_window">
      <field name="view_mode"
      >kanban,tree,form,calendar,graph,pivot
      </field> 
  </field> 
  
  <!-- Add Kanban view --> 
  <record id="todo_task_kanban" model="ir.ui.view"> 
    <field name="model">todo.task</field> 
    <field name="arch" type="xml">
      <kanban>
<!-- Empty for now, but the Kanban...
