as it is used in https://github.com/kivymd/KivyMD/blob/cfe5aac30f50708c6208c8b33b0ef1aa390721e8/kivymd/uix/tab/tab.py#L1095

Now I understand that indicator animation is different from active tab switch animation. However, if I set indicator_anim = False I also would expect the tab switch not to animate. If that is intended, then I would expect a new variable to control this behavior, e.g.: tab_swtich_anim = BooleanProperty(True)
