Easy Shulkers!

Creator notes

This datapack allows you to open a shulker box without placing it down. Just hold the shulker box in your main hand and it will appear in a minecart in front of you, allowing you to quickly access its contents without having to place it. You cannot put shulker boxes inside of shulker boxes with this method. I could have made the minecart invisible, but that would have required a resource pack and so would have made installation a lot less convenient. I am aware many other datapacks exist to do this too, but all of them have slightly different methods of doing so. This is what I feel is the most vanilla and least intrusive method of doing this.
