It really has went too long without being able to directly give something to players straight from your hands, the dropping on the floor and saying "here" feels way too outdated and frankly idiotic at this point, so I hope that changes soon with an addition of a 'give' mechanic where your character simply points out an item and others look at it and press F to take as they would any item.
The key could be set as any random unused key or simply like an F1-F11 animation, doesn't matter. It just needs to be there.
