I am using theme 2.8. The quicklist feature works for all sizes of monitor except when you resize the screen to the smallest size or use it on a phone. At that size the plus symbol disappears and you are not able to add items to a quicklist.
Is there a way to activate Quicklists for the smallest size? I have looked at the code and see where it originates but cannot find what controls it's disappearance at the smallest size.
