+ * @class MasterEditor
+ * @brief The MasterEditor class represents the main editor for a ROM in the
+ * Yaze application.
+ *
+ * This class inherits from SharedROM, GfxContext, and ExperimentFlags, and
+ * provides functionality for setting up the screen, updating the editor, and
+ * shutting down the editor. It also includes methods for drawing various menus
+ * and popups, saving the ROM, and managing editor-specific flags.
+ *
+ * The MasterEditor class contains instances of various editor classes such as
+ * AssemblyEditor, DungeonEditor, GraphicsEditor, MusicEditor, OverworldEditor,
+ * PaletteEditor, ScreenEditor, and SpriteEditor. The current_editor_ member
+ * variable points to the currently active editor in the tab view.
+ *
+ * @note This class assumes the presence of an SDL_Renderer object for rendering
+ * graphics.
