SBuild (Schema Builder)

🛠 In-world preview — a semi-transparent hologram of the build at the X/Y/Z location while the GUI is open (moving the cursor moves the hologram). A highly popular feature in similar tools. ↩ Undo — restore blocks to their original state if you don't like the build (requires saving a world snapshot before construction). ⛰ Air cutting — an option to "remove air via the schematic"? Specifically: when placing a build into a mountain, the empty space within the schematic carves into the terrain (or simply: "Paste air" — overwriting existing air blocks); this solves the "buried house" problem. 📏 Snap to ground — automatically lower the build to the ground level or the first solid block.
