Feature Description

Currently once we modify the playback tempo on a video it will always stay the same unless we change it back. For me this is unintuitive because whenever i change the tempo i only want it to be applied to my currently watched video. Because of that i would love to have an option to reset it so that i don't have to reset it by myself everytime i modify the tempo speed.
