So I decided to port over AES_CommandControl, and it went...disturbingly without any problems which has me a bit concerned.
No but really, this went almost too well, so I expect bug reports. Anyway!
This plugin lets you do all sorts of fun things with actor commands. Copypasta'd straight out of my github:
Able to enable/disable attack, guard, and item globally or on an per character/class/equip/state basis
Can replace the attack command, optionally requiring certain conditions to be met in order to do so such as less than 50% hp, affliction by a certain state, etc
Able to move certain commands, such as guard, over to a left or right sub-menu
Can re-order commands by type (attack, limit, single, skills, guard, item, etc)
Can unleash special abilities when using basic attack, based on certain conditions combined with random chance
Can seal the item command on an actor/class/equip/state
Can set single skills on the actor command window, similar to attack
Able to repurpose TP into a limit break resource, showing a special command once TP reaches a certain threshold--either temporarily overwriting the attack command or appearing as an extra, temporary command in the actor command window
Can apply states when an actor guards in addition to the standard guard effect. These effects can be applied to either the user or even the entire party
Edit: The terms of use can be found in the readme there and should be reviewed before using, but in general: free in commercial and noncommercial alike, just give me credit, don't try to pass it off as your own, etc.
