The original Display creatures looks like this, showing only the enemy's name, number (in case of more of the same unit) and distance.

My proposition would be something like this. I removed the distance, since it can be a bit redundant, I'm not really sure if it's really that necessary. The resists could be made with icons instead, green being positive res. and red negative res.
Status could be managed the same way.

I have no idea if this can be implemented. But for now, the Display creatures isn't really useful, personally, I just check it when there are mobs off-screen and I'm too lazy to press the 'l'.
What do you guys think?
