As far as I know there is no way to assign weapons as Favourite
You could also save “Preset” with weapon 1 / weapon 2 / curio 1,2,3 and with just a click it changes all that
It would help a lot as some of us keep every weapon we found interesting for when the full crafting system is on. I have now 24 melee and 19 ranged weapons and only use 4, but have to go through each one to remember the correct one.
Thank you love
