I was thinking, since beta 1.2 adds walljumping (which currently doesn't really have a use now since you can fly, beam jump, etc.) what the ESF team could do is when chars are not charging up, using turbo, or charging up an attack, they don't show up on the radar. That way walking, wall jumping, etc would be more useful and it would also portray the anime a bit more, since DBZ chars did supress their ki at times to avoid enemies (IE: DBZ fighters climb the mountain to avoid detection by Frieza and King Cold, Imperfect Cell supresses Ki to hide from Z fighters.)
