One of the great things about Evernote is that it can be used for so many things: text, picture, and audio notes; file storage and archive, blogging, task management, project management - all with the most powerful, scalable search I have ever seen. The problem with Evernote being so powerful, with so many uses is that it is sometimes hard to find the exact Note that is needed. This means that if you use Evernote for task management, it can be a challenge to find your Todo list just to enter a new task and checkbox.
Workflow makes the process of entering new tasks and checkboxes in Evernote extremely simple and fast which is exactly how task management should be. If you are spending a lot of time entering tasks, then there is something wrong with your system. This simple 4-action Workflow asks for the name of your task, automatically adds the checkbox, then creates the task with the checkbox in the Evernote Note that you use as a task list. The whole process takes less than 30 seconds which is exactly how task management should work - easy, quick entry of tasks so that you can spend more time doing those tasks rather than recording them.
