I would like an feature that allowed us to make a list that for personal uses, so I can keep track of pricings, but without it going public just to make sure I do not oversell or undersell my items without including any images until I am completely willing to sell my items and therefore until then (if ever?) I put up some images of the items that I want to sell.

I Have a graded teenage mutant ninja turtles (fcbd) 2015.  Can't seem to find it to add to my collection 

When you go to view your collection give the price for the single card not the total value if you have multiple 

i have some of spain cards and i can't find spain version of lycanroc vmax

Please add a filter to exclude unlicensed games.

This would help in sorting for people going for complete Licensed sets. Namely for NES.  For example when I sort by highest price first to map out what heavy hitters I still need, it gets cluttered with unlicensed games.
