About this Mod
Command Block Editor
Command Block Editor is a utility mod that makes creating and managing command block systems much faster and more convenient.

Perfect for map makers, technical builders, and anyone who works with large command block setups.
Opening the Editor
Press the configured keybind (default: =) to open the editor.
- If you are looking at a command block, the editor will open with that command block's commands loaded.
- Otherwise, a new command block will be created at your current position and opened in the editor.
- Press
Ctrl + Sto save and close the editor.
