You can now natively send players messages using the normal color codes, by adding a custom command in to the commands list, please note that the player doesn't actually execute the command, and the message is handled within the script.

Dynamic inventories differentiates the player's open inventory from their personal survival inventory, so that they can move around objects in their main inventory separately from their open one, this has bugs and isn't fully working, use at your own risk.

Please note that this is optional, and you have to enable it in the options section at the top of the script.
