It's a neat feature, but we might want to give the option of manually toggling the AC display per creature as well.

So the default behaviour is that the GM can toggle the AC display in the player view for individual creatures, and then your solution is a QoL feature that GMs can opt in to use to reduce how much they need to toggle.

Would you be able to add the toggling behaviour, then I'll look at pulling the feature?

Thank you for the feedback, I'll take a look. Since the GM is probably more focused on the default encounter view, I'll try to add a toggle there (maybe in the 3 dots menu, something like "Reveal AC")

I added this option now:

To be honest, I prefer this solution to my initial idea and would probably remove the general option. It's more elegant that way since it leaves more control to the GM and also reveals all creatures of the same type at once, instead of just one. What do you think?

The only thing I'm unsure about is the slightly long wording in the dropdown

I improved my implementation now again. I did leave the original setting in their and also added a second setting for the gm to decide if they want to reveal the ac of all creatures of the same type at once.

The only thing I'm still unsure about is the reveal in the dropdown. Do you think it would make more sense in the Edit View of a monster? Or maybe even in both places?
