Here's a tip for stripping the Google Ads code out of the application:
-- Point at the application icon and control-click. From the pop-up menu that appears, choose 'Show Package Contents.'
-- This will display the application's contents as a bunch of regular Mac folders. You'll see a basic folder and one for each of the viewers.
-- Open each of the folders, locate the file named 'index.html,' and open it with a text editor such as TextEdit or TextWrangler.
-- Edit out the ad code and resave. You might also want to add your own page title or even customize the HTML a bit.
Now when you use the application, it will build pages with your edited code rather than the original.
