Yeah, I think jump in exploration mode should be automated (since actions don't really matter). It's clearly possible since the "following" party members can auto jump once the first character clears something.
In combat, it obviously makes sense to keep jump the way it is now since right now it consumes the bonus action.
Alternatively, they can just follow PnP where Jump is a part of your movement so you don't really have to worry so much about it.
