Loot Table Rewards should feel more like a real chest (no auto-inventory)
Currently, I get my random loot able rewards from the function called Loot Table Rewards. I will put a right-click trigger on a chest for this. This works really well, and I like the /md loot interface. The only issue, and my players have complained a bit about this, is that when a player clicks on this chest... whatever is inside just gets thrown into their inventory. ("auto-inventory") This is very unnatural behavior for a Minecraft player. They like to look at what's there, select things, move them to where they want. As you know, MC defaults this type of activity to the hotbar, so it slows down action to have a player stop and carefully rearrange their inventory hotbar.
I'd imagine this might be difficult since this is more like a POP-UP than a real chest, but you should consider improvement here.
