Is there any need to talk about normal throws? I'm sure there's some combo potential with them, thus a need to differentiate between fA (attack) and fA (throw). Also, I feel like jB might not be concise enough. It's fine for the start of a combo, but what about attacks that need to be executed while still airborne, before landing? Would we also need notation for continuing a combo on ground?
Ex: jB jB jB could be J, B, land, J, B, land, J, B, or it could be J, B, B, B, land.
If there isn't a method for denoting this yet, maybe brackets after "j" for any aerial combos, and anything outside of the brackets revert to being assumed they're performed as grounded attacks?
Also, I'm aware that all this is speculative on moves/combos that may or may not exist yet, but it never hurts to be prepared.
