Reorganizing tasks is no simple click and drag. There are a few steps. First click on the photo stream thumbnail of the task you would like to move. Next to the thumbnail should be the outline of two arrows in between a folder outline and a trash can outline.
Clicking the two arrows will open a pop-up screen. This screen is our task moving screen. On the top are two options “to the left of” and “to the right of” that describe where the folder will be placed. Then click on one of the tasks pictured that you would like to move your task to left of or to the right of. Once all selections are chosen click on the move button to replace your task.
