You can track personal tasks on your Viewpath Today page. These tasks are not related to any specific project, and will only appear on your Today page. To add a task, simply click the "+" in the lower left hand corner and then use in-line editing to change the details.
Once the task is complete, it will be removed from your current view. You can show completed tasks, including both project-related and personal, by clicking the filter icon under the "Undo" button, and de-selecting "Hide Completed Tasks".
We currently do allow personal tasks to be deleted, but you can simply mark them 100% complete to remove them from your view.
