iPulse is somewhere off screen, and I can't find it to bring it back. How can I reset its position?
 

To reset iPulse's location on the screen at launch to its default position, hold down the Shift key while opening the app. This will move iPulse back on screen and show the Quick Setup screen where you can reposition it to your heart's content!
 

(If you're using iPulse 2, hold down the Option key instead.)
