I think it will be a good option if the quick Adsense plugin can display ads unite(s) according to the visitor device type (sometime by using the user agent).
For an instance if the visitor come from a desktop computer, display already given PC ads unite, if the visitor come from a tablet, display the already given tablet ads unite, if the visitor come from a Smartphone display its relevant ads unite.
The reason for this request is, when we use a responsive theme with the latest Google responsive Adsense unite, it's hard to display the correct ads unite to desktop PC as well as tablets.
For an instance, I use use advanced responsive Adsense unite to and customized it to display 300x250 ads unite if the screen resolution is greater than the 800px. However, this system not working if the visitor uses a tablet device. Because some tablets have 800px resolution too. Therefore tablet user above the fold large part, cover 300x250 ads unite and content has less space (beginning of the posts ads unite align left or right situation).
With a latest Google search engine algorithm update, I think this will be a good feature to give more priority to the above the fold content.
