If you operate on a split screen (like me, laptop on one side, monitor on other), it’s a bit more convenient.  Anxiety provides a small partially transparent window on your screen, that stays on top at all times.  You can display any calendar you’d like.  So if you have tasks on multiple calendars, you can flip between the different calendars with ease.  Once you check off a task, it turns green, blinks and then softly disappears (actually displacing your anxiety with a nice finishing touch).  Explaining this app doesn’t fully do it justice, so I invite you all to give it a try on your own.  I’m personally addicted, and my anxiety is now at a controllable level… sigh.
