can we have a subject header in task separated from the text body, so in other word when I check my task I see just my subject and than when click on one I will see more of the task
Thank you for your feedback, we will consider adding such feature in the future and you're welcome to add your suggestion as a request to our Votebox: http://todoist.com/Vote/
For now, as a workaround, you could add notes to tasks. You would only see the task's name by default and the note icon. Clicking on the note icon will show you all notes it contains. You can even upload files into task notes.
