So one issue that I've just noticed (since I just used the friends list for the first time) and I'm sure all of you have already, is that regardless of what I registered your name under, is only goes by your Mii name, so If I just added a bunch of you all at once, and then you all accept and add me back at the same time, the only way I know who was who (assuming your Mii name isn't the same as your forum name) was to either memorize what order I added you or check this thread for Mii names.
It would be nice if maybe the name i assigned for everyone I registered was in grey behind everything and the Mii name up front so that you know immediately who you're playing with.
