Custom keybinds will not work because buttons do different things depending on what your character model is doing, whether in inventory, just standing plainly or in fighting/combat stance.

I would be desirable to also be able to change fire modes without having to raise weapon like in the games current stable patch and previous ones.

The A button only swaps the item with whatever you’re hovering over in inventory on default controller settings. A is used to combine only if you choose the “new” settings in controller under the inventory tab.

This is definitely needing a fix hopefully before this patch comes to stable. Especially because when switching from a two handed melee weapon to a gun stored on the right or left shoulder the two handed melee weapon (or other weapon like a scorpion that takes up less item slots) will then be stored on the shoulder and if there are not enough slots available you then will not be able to stow the weapon in your hands without dropping or dragging the other item into clothing or backpack slots.
