Lovic's Better Command Block

Right-clicking a command block, a command block minecart, or holding a command block item opens a redesigned editing screen. The editor shows a wide multi-line text box that wraps lines automatically and scrolls vertically without jumping, with command highlighting, auto-completion that follows vanilla conventions, custom names, and detailed hover tooltips. Holding Ctrl and middle-clicking performs the vanilla Pick Block behavior instead. Edited data is saved directly into the item's NBT and applies once the block is placed in the world.

The mod targets map makers, command creators, and server admins who write and reuse command blocks often. A preset system and an export and import feature for .pvic templates let users share configurations through the config folder that VicColor also uses. Pressing Alt+C on a targeted block places its x, y and z integers on the clipboard, rounded the way vanilla F3 and data copy round them, and a chat line reports that the copy succeeded. The mod is client-side only, so a server does not need it, and it is open source under the MIT License. Files are published for Fabric and Minecraft 1.20.1, with Fabric Loader 0.15.0 recommended and Fabric API required.
