Better Command Block UI
Tired of constantly holding down arrow keys to reach the middle of a long command, only to overshoot and spend an eternity backtracking? Wish you could see the entire command in a structured format without needing to copy it to external software and back?
This client-side mod addresses these and many other issues by completely overhauling the command block interface.
Main Features
Multi-line Command Input Field
- Automatic indentation formatting based on brackets
- Color coding of nested NBT data
- Line wrapping
- Horizontal and vertical scrolling
- Improved text selection and deletion
- Adaptation to interface scale and window dimensions
Redesigned Button Organization
- Command block state buttons converted to compact icons with tooltips
- New button for switching between viewing the command and its output
Command Block Chain Navigation
- Buttons for moving forward and backward through the chain without closing the interface
- If multiple blocks point to the current one, all are displayed with their directions
Additional Tools
- Save button and CTRL + S shortcut for saving without closing the interface
- Tools window with rotation selector (outputs radians) and color picker (outputs integer and hex code)
- Hotkey for area selection (press ; to select two opposite corners of a volume)
Configuration Settings
- Fully customizable indentation behavior
- Optional automatic saving when closing the screen or moving along the chain
- ModMenu support
Compatibility
The mod is compatible with NBT Autocomplete, Component Utils, Better Suggestions, and Better Highlighting.

As mentioned earlier, the mod is entirely client-side. It receives the command from the server and displays it in a multi-line format with indentation, but doesn't actually add line breaks to the command itself.
