When you select Show HP in options, they had 3 options
1 - Detailed (Show FP and HP to player)
2 - Status (Show an description)
3 - Off (Shpw nothing)
I do this but to a new field a Shield HP field
I know this is good only for shield and Medieval campaigns
But I think is a good add to game, because we can "automate" the damage and hit points of the shield without need open a note for example.
