This is just an issue to collect some of the suggestions I may add in the future into one place. Nothing on this list is final.

Functional blocks

• Clay urns: chest like block with limited storage, but a mechanic for urn breaking (like terraria) and early game shulker box.
• Flower pots, possibly multiple sizes. Needs to support modded flowers.
• Clay furnace (kiln). Like a blast furnace or a smoker, but for ceramics.
• Clay pressure plates or other basic redstone components
• Some form of the faucet which has an on/off state instead of a toggle state, to allow an always draining barrel. Alternatively, somehow allow that to be possible using redstone
• Golems

Decorative blocks

• Clay tiles: carpet like block with fancy patterns
• Something like glazed terracotta, but with porcelain. More consistent colors with the dye color instead of normal glazed mix
