And before anyone asks, no, I don't find myself hitting the wrong keys more often using this layout. The old iKeyEx layout was fantastic, as you could choose the punctuations you used most often and line them up along the top row, which sped up typing no end. It won't be possible using this because of Winterboard limitations, but I hope one day the author of iKeyEx can bring a version of that extension into the 4.x arena.
