Well speaking of L1 Button getting nervous, I just want to point out like Economizer did that I've always enjoyed the use of O Button as many others as it offers a nicer visual than a cap O when describing that you've acquired something you're proud of or to say a short "yes, I have this" for search messages. Same for the X button and "No, I don't have this". For anyone that isn't aware you just find these under Controller menu, select them to AT and hit backspace to delete the word "button" so yeah. Some of the apparent useless ones do have an use but I suppose if they must go in favor of more communication convenience then may I suggest they be the very last ones to go in the hopes that they might be saved.
