Tired of holding down your arrow keys to get to the middle of a long command, only to overshoot and spend another half an eternity backtracking? Wishing you could just see the whole thing in a more structured format without needing to copy it into external software and back again? Better Command Block UI Mod (1.21.7, 1.20.1) intends to address these issues by overhauling the Command Block UI, mainly by extending the single-line command text field into a multi-line text box, complete with vertical and horizontal scrolling as well as automatic parentheses-based indentation! Additionally the large buttons used to cycle the command block type and toggle things like powering mode have been reduced to simple icons with tooltips, and an extra button has been added to switch between displaying the command and the previous output.

Features:

UI Enhancements:

  • Multi-Line Command Editor: Write and view long commands across multiple lines with automatic indentation based on parentheses.
  • Color-Coded NBT Data: Nested NBT structures are visually highlighted for easier debugging.
  • Line Wrap & Scrolling: Both horizontal and vertical scrolling supported, plus wraparound for long commands.
  • Improved Selection Tools:
    • Click-and-drag selection
    • Double-click to select words
    • Ctrl+erase only removes full words (not entire NBT blocks)

Command Block Navigation:

  • Chain Navigation Buttons: Move forward/backward through command block chains without leaving the UI.
  • Block Direction Tooltips: See which blocks point into the current one, with directional hints.

Extra Tools & Utilities:

  • Rotation Selector: Outputs radians.
  • Color Selector: Outputs integer and hex codes.
  • Area Selector: Press ; to mark two corners and auto-generate a selector string for commands.
