Project Management the Wrike Way
TaskPaper makes it easy to create a list of your projects and their tasks so that you always know what needs to be done. It's simple to reorganize the list, create new items, mark items as done, and delete items that you're finished with.
You can also assign contexts (such as "home", "office", or "car") to your tasks so that you can later generate lists of all tasks assigned to a specific context.
