If you add frames to moves that put you in freefall, wouldn't that make it so much easier to cancel out of? It would pretty much simulate not being in freefall at all.

I only posted it a minute ago, but I thought you guys would know some of this stuff too, any help is appreciated
Do you have sm4shcommand running? if so, look at the guide in the thread, and then to edit the hitboxes, look for the command (I think jab's attack12? To be safe maybe edit an aerial AttackAirF etc or a smash attack, the s4 attacks, tilts the s3 attacks, and near the bottom the specials. I'm not sure how the extended hitboxes work, and some characters don't change when you try to change the speed of their chargable attacks.
