To get the button to show, simply hover your mouse over the ad row for a second and it will appear on the right side of the ad. A short 1 second view time is required by the ad network, but it will remain gone until you refresh or leave the page (though some actions like sorting can bring them back... unfortunately that's how the table works and I don't have time to recode that part from scratch). ***reinserting ad issue resolved here***
A gif of the process... The gif is slightly slowed down because I suck at making them:

Note: Not available for small screen resolutions (i.e., mobile phones) since the UI is totally different, and there's only a single ad anyway.
Note for Tablets: To get the button to show for tablets, you may have to tap on the row (to the side of the ad).
