Thanks for all of the hard work md_5! The fact that Mojang made each Shulker box has its own color makes sense because it needs the direction value, but it's also worrying because it is using up the diminishing pool of available values. There are only 20 left! Implementing a new file-system will result in much greater world-storage sizes that I am not looking forward to. If they just change all of the IDs to use the ~2000 that are available, that would complicate things and require file conversions. Hopefully 1.12 will add more features that help servers, since this update didn't focus on that. Hopefully they can somehow get PVPers willing to update (It's a haunting pain to everyone that players are still preferring and sometimes demanding 1.7). 1.11 is good mostly for single-player.
