'I found a way to view all the items ever viewed in the discovery queue. You go into Store > Explore > (at the end of page) Help > Support > My account > Data Related to Your Steam Account > Scroll down to "Store" category and click Discovery Queue History in whic you will find Discovery Queue Apps Viewed'.


So:
Store - new Queue list - very down: Support - 'Data Related to Your Steam Account > Scroll down to "Store" category and click Discovery Queue History in whic you will find Discovery Queue Apps Viewed'.
