I use styles a lot in Mellel, with F-keys, and usually have to place a label on every F-key to remember which style they refer to. So when I saw the Touch bar in the new Macs I first thought of Mellel and my Function bar. I hope Mellel can soon have an integration with Touch bar with keys showing the style they apply to the text. Doesn't sound like something too difficult, right? BTW, MS office has already updated their apps to the TB.
