The game has large amounts of different guns. Like in Borderlands. A 5 minute fight will lead to 10 minutes of inventory management. It is hard to tell which one is your favorite gun or which one is new or junk or gun that I should check or whatever. The only way to mark a weapon is to attach some mod.

Proposition

Every inventory screen showing weapons should have buttons for:
- disassembling (hold Z) (I see this is done already)
- putting into a weapon slot (1, 2, 3) (There is menu in backpack already, but not hotkeys)
- marking weapon as favorite (any hotkey)
- marking weapon as junk (any hotkey)
- drop weapon (X)

Stuff marked as favorite should be harder to sell or disassemble.

Of course junk and favorite marks should survive saving and reloading :)

Edit: add drop weapon

I'd also like buttons/hotkeys for "Disassemble all" and "Sell all" in all relevant screens. You can't even confrim the defaullt amount of 1 with usual key (F).

There are hotkeys and even weapon wheel so idk what are you talking about. Junk and favorite... maybe after whole bug fixing.
