Everything you mentioned, except "make shulker box alble to stcik at walls", is actually beyond MineClone2's target. We aim to imitate Minecraft Java Edition 1.12, and the features you mentioned are all from newer versions. There have been developments for features from newer versions tho, check out https://git.minetest.land/MineClone2/MineClone2/src/branch/mineclone5.
Thanks for mentioning the shulker box issue, we will work on that.
