Crust is a code library and testing toolkit designed to make some people's lives easier and provide some very basic gameplay features. Everything is configurable.
The testing toolkit:
The primary feature of this toolkit is a set of customizable and keybindable command-driven buttons added to the inventory screen. There are currently 19 built-in buttons and 16 user-defined buttons (pick its look and slap in whatever commands you want it to run). As an added bonus, the mod allows you to configure the default game rules for newly created worlds.
Crust modes:
Additional player capabilities mainly for testing purposes. The starting modes for new players, required OP level to change each mode, some client preferences, and server limitations are all configurable.
By default, the only mode that is enabled for new players and does not require 'cheating ability' is Magnet.
Available modes:
