We've just added a handy new feature. Now when you press pause on a task the Today's Tasks widget will appear above the Play-Pause widget on the bottom right of your screen. 

All the tasks planned for the day will appear on the list and you can press play on the one you want to work on next. This way it's easier to move from one task to the other.

When you have no more active tasks for the day the Today's Tasks widget will disappear.
