Blocks²
by Mike
Blocks² lets players stack two or more blocks into one position, such as a lever inside a fence or a sign inside a trapdoor.
What it does
Sneaking and right-clicking with a block in hand places it into a position already holding a block, so several blocks share one space. Each block inside a stack keeps its own block-state properties and shows its own breaking animation, and removing one block from a stack leaves the others in place. Four trapdoors can sit together in one block, with a carpet and a lantern beside them.
The idea is to lift the one-block-per-position rule that vanilla enforces. Blocks that fully fill a space block everything else, while most transparent blocks such as leaves and glass can share a position with other blocks. Signs can be placed on standing or wall positions, support full text editing and dye or glowing ink, and can be combined with other blocks in the same space. The mod is set up through a changeable config, and it is client and server, so the server and every player need it. Blocks² requires Fabric API and is published for Fabric only, currently for 26.2.
Key features
Multiple blocks per position
Sneak and right-click places a block into a position that already holds one, so several blocks occupy the same space.
Independent block states
Each block in a stack keeps its normal properties and its own breaking animation when it is removed.
Stacked trapdoors and signs
Four trapdoors, a lever in a fence, or a sign with a trapdoor can share one block position in the world.
Transparent and solid rules
Fully solid blocks occlude everything else in their space, while leaves and glass can share it with other blocks.
Changeable config
Settings can be changed in the config file, which controls how the stacking behaves.

Use cases
Compact decorations
Builders can fit lanterns, carpets and trapdoors into the same space to decorate rooms without extra blocks.
Shaders and other mods
Shader packs work with the mod, and some other mods are reported to work alongside it, though not all block entities are fully supported.
Who it’s for: Builders and players who want more detailed decorations in a single block position. Server owners who run the mod should be aware that hanging signs are not yet fully supported and that some block entities and Create blocks display only visually.
Questions
Does Blocks² need Fabric API?
Does the server need Blocks²?
Are all block entities supported in stacks?

What the author says
Combine multiple blocks into a single position. Stack a lever inside a fence, a candle on a trapdoor, or two trapdoors and a sign into one block — each block should work exactly as it normally does. The main idea was to remove the "one block per block" rule, as weird as that sounds.
