# menu_main_15505_enabled - controls enablement of the NickelMenu button on 4.23.15505+
# menu_main_15505_label - sets the label used for the NickelMenu button on 4.23.15505+
# menu_main_15505_icon - sets the icon used for the NickelMenu button on 4.23.15505+
# menu_main_15505_icon_active - sets the active icon used for the NickelMenu button on 4.23.15505+

# main_menu_15505_<main menu option> - controls the added NickelMenu button
# main_menu_15505_<n>_<main_menu_option> - controls the main menu button at position n (indexed from 0)
# note that there may be already-hidden buttons in the list:
# on a Kobo Libra Colour running 4.41.23145, the button list is:
# 0 - Home
# 1 - My Books

# menu_main_15505_enabled - 0 or 1
# menu_main_15505_label - the label to use instead of "NickelMenu"
