Build a large DIM Wishlist.
Do you find it cumbersome to add every...single...barrel into a wishlist when all you really care about are the two main perks, and maybe the mag perk? Needing to know every single perk hash and adding that permutation can be a pain. Worry no more.
This extension adds a sidebar on the right of D2Gunsmith that allows you to add the current weapon and its selected perks to a textbox that you can copy or save to a separate text file. It will organize the list into a format understood by DIM with comment fields for notes. Use the radio buttons to specify the type of roll that is being added (PvP, PvE, or GM). Use the "INSERT" key to quickly insert the newly selected roll into the wishlist, eliminating the need for an extra mouse click.
