It would be amazing to be able to quickly create a new task in the task drop-down box.

In this screen shot I quickly went to set the timer and realised I needed to create a new task as the tasks there didn't fit with what I was doing. I then had to go out of this area, go to the client area, projects, tasks and create a new task. Being able to create the task on the fly in the timer would have been so much faster.
