Canvas Resizer for Facebook Games

Good idea to address an irritating problem with Chrome and touchscreens in particular. This app works once in a while, and fixes the problem. Canvas Resizer is let down by not having user controls to actually use the app...it doesn't resize anything unless the app detects a problem itself, which the app is spotty at doing. The only user controls allow you to hide or remove the app. It would be perfect if the user could decide to resize at any time.
