In some instanced battles, there are some mechanics where every single party member will get some sort of icon over their head, and the oncoming attack will require some level of coordination from everyone depending on those icons. But, at times it's hard to read your own when there's 7 other icons. Sure, it's possible to figure it out by spreading out and wiggling, but I think this could be cut out entirely with an option to only render your own marker and perhaps a party member's closely related one like in magnets, for example. Most mechanics that come to mind for me with markers almost all require little adjustment based on other party members. For mechanics that genuinely depend on knowing each person's mark such as the original Limit Cut or magnets, there could be an override of this function.

I got this idea when I saw some of the mechanics in Delulbrum Reginae, with the Hot and Cold and queen's march only showing your own mark, giving it a lot more visual clarity than if it showed you everyone's.

And; if this trips some unforeseen consequence in some specific fight I didn't remember; at least make mechanic icons render over party menu markers. I've been memed on before when I couldn't see whatever polarity I was because the (Target to Attack 1) marker was covering it, and I can't think of any situation where being able to see it would be more important than seeing the fight's marker.
