I've been meaning to add it to the pack for ages... Hm. It would take some serious doing, and I'm a bit bogged down in other projects at the moment. I wouldn't expect it any time soon, but it'll definitely come with the next update.
As I've said many times before I love your work all of your icons are fantastic. There seems to only one thing missing The Seal of Rassilon. I've tried making one myself but it looks horrid everytime I try. Do you think you could try making one in the future?
