Track Minecraft build progress by layer

Mark completed work by Y layer and keep the progress tied to the source file SHA-256 across a reload.

01

What to do

  1. Progress belongs to the exact imported file, not merely its filename.
  2. Use the current layer as a short construction checkpoint.
  3. Keep a source backup because local browser data can be cleared by the user or browser.
02

Privacy and reliability

Files are parsed on your device. In the viewer, the original is also kept in your private library after the storage notice and stays private until you publish it; the standalone converter never uploads anything.

TipKeep a backup of the original. Browser conversion is convenient, but it does not replace world backups or source control.
