 * Thank you for this plug-in. Great work.
 * I added the screen size function to my functions.php file, but can see no change(
   the Galaxy tablet option does not show up). I also tried adding it to your responsive-
   page-tester.php file on the off chance it was meant to go there. No luck. Do 
   I need to change the ‘mythemename_filter_rpt_sizes’ to match my theme name? I
   tried that too, no good. I appreciate your help. Here’s my site:
