Better Command Block UI
by Tec
With Better Command Block UI installed, the command block editor on Fabric or Quilt shows multi-line text with indentation, wrapping and nested NBT coloring.
What it does
The editor replaces the single-line command field with a multi-line text area. Commands longer than one line are shown across several lines, with indentation derived from parentheses so nested structures are easier to follow. The mod only changes how the command is displayed: it takes the command as the server sends it and does not insert any line breaks into it.
Selection and editing are reworked as well. Text can be selected by dragging, a double click selects a whole word, and horizontal and vertical scrolling let long commands be navigated. Nested NBT data is colored so its levels can be told apart at a glance.
Servers do not need it; each player installs it for their own game. The code is open source under the CC0 1.0 Universal license, and builds exist for 1.18.2 – 26.3 on Fabric and Quilt, including snapshot builds.
Key features
Multi-line command field
The command text is shown across several lines instead of a single long field.
Indentation by parentheses
Indentation follows the parentheses in a command, which makes nested arguments easier to read.
Colored NBT data
Nested NBT data is color-coded by level, so its structure stands out in the editor.
Line wraparound
Long lines wrap inside the editor, so no horizontal scrolling is needed to read most commands.
Better selection and erasing
Click-and-drag selection and double-click word selection make it quicker to edit a command.

Use cases
Editing long commands
Commands with deep nesting, such as complex execute chains or NBT-heavy data, are easier to follow when split across lines with indentation.
Map and datapack building
Builders who write many command block commands in a single world can edit them with the same tools they expect from a text editor.
Who it’s for: The mod suits map makers, datapack authors and players who write command block commands and want a more usable editor. Because it runs only on the client, it is also useful in single-player worlds and on multiplayer clients that connect to servers without the mod.
Questions
Does Better Command Block UI need to be on the server?
Does the mod change how commands are stored?

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?
