+1 I can never tell the difference between the red and blue mutagens due to colour blindness which means it takes forever to search for specific mutagens, different icons would be extremely useful. (The colour blind option doesn't change this, in case anyone was wondering.)
I would also a better icon for new items added in the inventory. The star symbol isn't enough when you have a large amount of items in your inventory. I would reccomend to a colored frame for new items.
