An ability where you can right click an item on another player to hand him stuff he can take for battle and use anytime like healing potions and buff foods. This would help make medical kits or support kits.
I heavily prefer dropping items with Q. It's vanilla and feels like Minecraft and there's less forcing and less ambiguity. I disagree with the suggestion (but support it's intention/goal of the suggested mechanic)
Also means we have little to no code to write to support that.
I support handing stuff directly instead of dropping it, because dropping stuff on the ground can get buggy and lead to other players steeling it. Though I am not entirely sure how to make it intuitive without also making it happen accidentally.
