I use something similar. Ring Toggle. It looks like a Bell
I can easily switch between Ring, Ring and Vibrate, Vibrate and Silence with a few touches. I use that widget about a dozen times during the day. Switch it to vibrate when I get to work, switch it to silence when headed into a meeting with the boss, switch it back to Ring or Ring and Vibrate as I leave work. I have an app that can do this for me based off my GPS location but after a few times where it didn't work properly I switched to the Ring Toggle widget. My phone started going off during a company meeting where the owner of the company was talking about the business and the direction were headed and RING, RING...Everyone looks at me :-( Not Good LOL....
