2) A user requested feature to remove ALL renamed items has been added more information available on the wiki: https://github.com/dniym/IllegalStack/wiki/RemoveAllRenamedItems

3) There WAS another bug with CMI's shulker code ( the one that lets you open a shulker without placing it) that allows players to put shulkers inside shulkers. This bug has been fixed in a recent update to CMI, all users are urged to update to avoid nested shulkers.
