CommandBlockUIOverhaul

Make command block editing clearer and easier.

CommandBlockUIOverhaul is a lightweight client-side mod that improves the editing interface for command blocks and command block minecarts, making long commands and nested structures easier to read and edit.

Features

• Multiline editing — Automatic wrapping, indentation, mouse drag selection, and scrolling.
• Hierarchy highlighting — Distinguish command and bracket nesting levels with IDEA Dark or vanilla color schemes.
• Configurable formatting — Customize bracket and comma line breaks, string formatting, empty lines, indentation, and line width.
• Live preview — Preview formatting and colors directly in the settings screen.
• Undo and redo — Keep up to 100 editing snapshots.
• Floating RGB palette — Adjust colors and copy decimal or hexadecimal values while continuing to edit commands.
• Improved command suggestions — Better popup visibility, positioning, and focus handling.

Formatting only changes how commands are displayed; it does not insert extra line breaks or indentation into the original command.
