I'd like to share a new small framework for creating and switching among multiple MFD page buttons, with little interaction with the internals. It assumes registering handlers in the MFD and calling them on typical Orbiter MFD events. Please comment before I release it more officially.
First an example usage in Launch MFD client class:
