Remove search_by_id() from frameline. - frameline is only responsible for drawing a row of frames. - layers and scenes are managed by MBScene_dom. So, function of search_by_id() must move to MBScene_dom class. - onCellClick() and _change_active_frame() are responsible for handling GUI event. - It should not be used with workaround to implement some function. - Solutions - MBScene_dom.find_layer_n_scene_of_nod() is used to replace search_by_id(). - MBScene_framelines.active_frame() is used to replace the workaround.
