There's a new #FinalFantasyV ROM hack on #RHDN, ReJobbed.
https://www.romhacking.net/hacks/9342/
And #FinalFantasyIV Job System version 1.5 has auto-sort for the inventory, you can buy additional copies of the jobs and (most important) you can un-equip all by pressing Select allowing for quicker job swapping.
Known bugs:
* Lance command will keep the command stance until next action is queued.
* Unequip all soft freezes on the character of slot 5 (4th slot from top to bottom) when inventory is full, press B to leave the menu fixes it.
* Unequip all soft freezes on the character of slot 5 (4th slot from top to bottom) when there is nothing to remove, press B to leave the menu fixes it.
* Using multiple copies of the same job is not fully tested out and may have unknown bugs.
