Kingdom Hearts: Chain of Memories uses a decidedly action-based combat system, and, as such, it makes more sense to categorize it as an Action RPG, especially with the Mega Man Battle Network games' categorization as such establishing precedent for quirkier action-based battle systems still "counting" as Action RPG gameplay.
This hack adds a star icon to each mastered Esper in the Esper menu. An Esper is mastered when all its spells are learned. There’s a version of the hack that draw a blue star instead of the user’s color (white by default). There are also two hacks versions that are compatible with Angelo/Silent Enigma Restored Ability Names patch. You can specify a different icon and disable star icon insertion in any of the assembly files.
