Old idea I'm bringing up but with a small twist:
Phantasy Star Zero has only ONE use for Select, and it is to switch between Chat and Map, but NOT between Stats, Chat and Map. So the idea is to modify whatever handles that to allow it to go cycle between Stats -> Map -> Chat -> <loop back>.
And maybe in the "Chat" screen, add a command via Select + Up, Left and Down to change battle plans between focus on a single target, spread our and heal, while Select + Right switch between Sync Photon Blast or not.
Though I really only worry for the first part, the second one could be for a future project.
