bookorbit/koreader-plugin/bookorbit.koplugin/bookorbit_main_menu.lua

--[[--
Main menu mixin for the BookOrbit plugin.

KOReader's side of BookOrbit: an icon in KOReader's top menu bar that opens
BookOrbit in one tap (in a book, the This book sheet), a trimmed Tools entry
for anyone who turns the icon off, and the openers for BookOrbit's own menu
sheet, settings, sync status and sign-in pages. Those pages load on first
use. Installed onto the plugin controller as regular methods.
