Code improvment: line <=> menu id function: In generell the structure of the menus is defined by the tStructure.h using global state defines. In some implementation hardcoded line numbers are used. Risk: In case the order of menu items change the update of other code sections could be forgotten (in the case the update of the top menu) causing unintended behavior. To avoid this the hard coded lines have been replaced by a function connecting the intended function to the menu item defined in the tstructure.h.
