At the moment when a player should receive an item using the give command and there is no room in the inventory left, the item is lost.
Therefor I suggest to add an option to drop the item/s on the ground instead of dismissing them.

Thanks for reading.

I agree, and on top of this, a give all command that gives items to all online players. I don't recall reading anything about it.

Yep this is needed, it must be added as soon as possible, also the option to change the item names when the msg that you receive an item appears.

There's a config option for this called drop-items-if-full.
