Advanced Pomodoro features

#Must
- Option to change the pomodoro time from fixed 4 cycles of 25 mins and long break to what ever I want from 25 mins to 55 mins of pomo, 10 mins of short break and 20 min of long break. (I mean flexible pomotimer should be there.)
- Timer widget on the menu bar in mac os and home screen widget on the mobile.
- White noises and other background sounds to focus to.
- one should be able to access all the tasks from the Focus timer screen itself. Similar to your calendar implementation (I can access all the task in the calendar window itself... so it becomes easy to calendar box the tasks)

#Nice to have
- some more background images
