Important
Important contains all tasks with high priority independent of list.
Use this view in combination with "Today" to get control over the most urgent and important tasks. You can also use the view to understand what tasks are important but non-urgent.
Mark any task "important" by using the quick menu 
or by drag and drop to the view "Important".
Change priority of a task by selecting the task, use Edit 
. Mark the task "Important".
Tip! Every important task is given maximum focus in every list and view with a bold font. A way to arrange your work is to use "Important" to mark the tasks you want/need to complete shortly.
