For status effects, add special sound effects. i.e. a bonk sound for stun, an ice sound for freeze, a hammer/anvil sound for protect, etc.
In the Photo mode, allow for the knight’s weapon to be on the back, as it is in the battle preparation screen view. Or perhaps even other poses. i.e. sword staked in the ground.
A long time ago, an additional battle text was added (milti-kill, over-kill, etc.). I personally always thought it didn’t add anything except screen clutter, and that visuals were better without those changes. Legible damage numbers are a better visual.
New weapon type: bows - Hits enemies in back row first.
