There are a few of things that I would like to see improved with the UI in battle.
1) Add the ability to mouse over status effects to see exactly what they are and how long they will last.
2) Make it so we can click to view the enemy cards while picking item/magic cards so we can make sure we know what their effects are.
3) The monsters stand in front of the cards in battle so we can't read them and the text at the bottom moves quite fast. It could be better to allow us to scroll back through text and also to click to bring up cards to see their effects. This would help understand how the effects resolved to give the final result.
