Final Fantasy Hacktics

So, for the people that are consistently in this forum category, it's time to play the comparison game!

This is sorta mostly an extension off of the FFTA Abilities Spreadsheet thread, which has been immensely helpful.  Some information does not seem to have been found yet, specifically bit information concerning the properties of abilities have not been found yet it seems.  In any case, let me see if I can start it off with the following list:

Any Control Ability
Any Morph Ability
Crystal summons
Lawshift
Descent
Abate
JP Gift
Yellow Clip

Apparently, only these abilities do not contain a certain bit (property) that all of the other abilities do have, and I can't wrap my head around what exactly is that property.  (Prone to error of missing something from the spreadsheet)

Please use any resources possible, preferably the other forum threads, TFergusson's Mechanics Guide, or just by modifying the bits in the FFTA Ability Spreadsheet and testing it yourself.  It would be nice if we can fill out this spreadsheet.  It'd be so fun to mod this game completely
Blank Card

I was wondering how hard it would be to completely make a class up assuming that the sprites are going to be recycled basically.  There seems to be room according to what I see when I examine the random blank slots in the job hack application, but I was wondering if those blank slots can actually be manipulated.

Also, I was wondering if there's a way to lock jobs to certain characters like how the hermetic is only for that special character and whatnot.  Is it possible to make it so that someone like Marche can have either a new class or an already built-in class all to himself.
