An update to DayTasks now supports having line breaks in tasks. You can add all the details you want to any of your tasks and DayTasks makes it easy. Behind the scenes it saves your tasks in one line in the todo.txt file so it will always be compatible when using your todo.txt file from another app or device.
You can use Shift+Enter to add a line break to a task, or try out the Easy Line Breaks option to allow line breaks naturally when editing a task with just hitting Enter. If you turn this on, use Shift+Enter or Ctrl+Enter to save or update a task.
You can try out this update from the beta versions in the PPA now. See details on how to install on the DayTasks page.
