Yes, I sometimes added that to some battles to tell the player that is a tough fight but probably should remove them since none of the enemies is actually a boss character 
Anima for example is 90% incapable of emotion so he pretty much can't be scared
So I lifted the castle and found my mistress' scarf beneath it. +2 strength
And then I danced on the Iron Throne barefooted without cutting myself, while singing the Marseillaise backwards and playing three accordions simultaneously, each bringing to life a previously unpublished creation of Beethoven's. +2 skill
After that, I convinced a whole crowd that stat derivation is a good idea. +2 will

I'm at the very beginning of the game, during the announcement of the twins vs the orcs. On the party screen, "Inventory" shows up in yellow even when other tabs are selected. E.g. both "Attributes" and "Inventory" show up in yellow when looking at a character's attributes. (If I'm on Inventory, then Inventory is properly the only word in yellow.)
Dunno yet if this happens later in the game too.
Error, happened when trying to move to an empty slot.
