With the introduction of Curse of Osiris, weapons from the expansion were given a badge in the top left corner of their thumbnail to indicate they were an expansion weapon. I would love to see something similar done on all energy weapons to indicate the element type they are, maybe a badge in the bottom right corner. This would help in situations where we need to quickly switch from one energy type to another. It would also allow us to quickly assess if we have all the elements covered in our inventory.
