I'm not sure how you're using all 128 spaces tbh. I have one hot bar dedicated to combat jobs and chocobo commands, another devoted to my gatherers/crafters with a couple materia related things as well, a hot bar to bring up different macros, Sprint, Ethers and potions, and another for other misc items like maps and minions, with 4 hot bars locked off to a job... I actually have one hot bar completely empty.
