If you press the "Work View" button, only actionable tasks will be displayed in your list.
What is an actionable task? It's a task you can do directly, right now.
It's a task that is already "start-able", i.e. the start date is already over.
It's a task that doesn't have open subtasks, i.e. you can do the task itself directly.
It's a task that has a due date different than "Someday", since this kind of date is reserved for things that needs more thoughts before being actionable.
Thus, in short, the Work View shows you tasks that you can do right now. It's very useful when you want to get things done and to focus on the relevant tasks!
If you use tags, you can right click on a tag in the sidebar and choose to hide tasks assigned to this particular tag in the Work View. It is very useful if you have a tag like "@wait" that you use for tasks blocked by some external event (i.e. a phone call you wait to receive).
And finally, an important note regarding the Work View: since the Work View is updated instantaneously, if you edit your task while using the Work View, this task might disappear due to the change you just made (e.g. adding a subtask, adding a tag hidden in the Work View, etc.). To avoid this, it's better not to edit your task while using the Work View.
