# TODO: Ideally the menu buttons (add_button) will be replaced by a proper
#       menu control (basically multiple DropdownList controls where the headers
#       have fixed names and, while captured, hovering over a header changes
#       which list is displayed). The menu control should go under UI controls
#       rather than be unique to the Animation Editor.
