i think backwards edge grab will be added to the list. i hated that with fox if i forget to press the direction of the ledge after pressing up+b straight up, he'd fall to his death. it'll help when you're under the stage and trying to up+b to a ledge in the opposite direction as the center of the stage. i hope that made sense.
in other words, you know how sometimes you're under the stage in Battlefield, in Melee. Using fox's up+b to the side won't kill you because you're facing the wrong way. it's a welcomed change though i'll miss turning people around with link's boomerang.
oh yeah and this:
is a directional air dodge for all you skeptics. seriously, what more proof do you need? the mario one was obvious and then you declared it was because of his jump momentum which never happens in melee.. then one where yoshi air dodges down in the middle of ascending double jump which throughs your "momentum" thing out. then there's one where link air dodges down while being midway through a platform. this is the 4th directional air dodge.
