Timer: Ability to configure the session to auto start after break time of not

When i use pomodoro timer and set 25min for each pomodoro session , which have a 5min break. When the 25min completes the break time starts automatically -which is a good feature- but what is not good here is the auto start of another session. Sometimes in the period of 5min break when i take a little long to start again studying the automatic timer which was turned on by itself utilizes my time even when i am not studying.
