MPUtils Basic Tools is an add-on for MPUtils aimed at modpack makers: it adds an in-game changelog, an issue tracker (in-game form or web link) and a support button for the developer.
The changelog is edited with a built-in text editor once Edit Mode is enabled via config or command. Requires MPUtils and runs on Forge, Minecraft 1.7.10 - 1.12.2.
