Update 7 May 2016:
The item My next major project will be to convert all sub-menus (charts and lists) into modules so they can have individual enable/disable and access level controls. is now complete. So all menus now have configurable access controls.
Currently the sub-menus are NOT sortable though. They are automatically sorted into alphabetic order (A-Z) based on the displayed / translated names. I have no plans to change this, but happy to rethink that decision if there are strong views that manual sorting would be better.
