Menus
The Menus screen allows you to switch between pre-defined menu systems, these are typically menus that do not contain all of the functionality of the default menu and have been tailored to suit a particular style of gameplay.

This system is still a little experimental and there are not a lot of choices, eventually one day I hope to allow players to define their own menu bit this is a lot more complicated than it sounds and as such has not been deemed a major priority.
