Command Block UI Overhaul
Command Block UI Overhaul is a lightweight client-side mod that reworks the editing screen of command blocks and command block minecarts.
What it does
The editor gains multiline editing with automatic wrapping, indentation, and mouse drag selection with scrolling, which makes long nested commands easier to read and change. Bracket nesting levels are shown in the IDEA Dark palette and vanilla colors, so each depth can be told apart at a glance. A history of recent edits can be stepped back and forward.
Formatting is configurable: brackets, commas, line breaks, string handling, empty lines, indentation and line width can each be adjusted, and a live preview shows the result in the settings screen. Formatting only changes how a command is displayed, so the stored command is left as written. A floating RGB palette lets players adjust colors and copy them as decimal or hexadecimal values without leaving the edit. Command suggestions get better popup visibility, positioning and focus handling.
The mod is inspired by BetterCommandBlockUI and is built for focused, practical editing. It is published for Forge and NeoForge, with a file for 1.20.1 and one for 1.21.1, both released on 2026-10-06, under the MIT License, and its source code is open.
