I noticed quickly when playing the game, that after a victory when your playing an AI, it assigns the AI a fake handle, which is fine, but from what I could tell there wasn't any way to determine the AI difficulty since it wasn't in the AI's name.
(I'm trying to post a screen shot but when I copy it in here it produces pages of code once posted for some reason and the image option seems to only link images from URLs)
I would recommend adding it next to the name at least that way you are aware of what difficulty you just defeated or lost to.
