I suggest to give the My Book Live (MBL) a key for shut down / shut off and the same key for startup / turn on power. I use the MBL mainly as media store and media streaming with my TV device. There is mostly no computer available, which can be used to shut down MBL.
The TV device has an internet browser (Opera) to call the MBL dashboard, but the user interface of MBL cannot be completely used without a mouse, so using Opera on my TV device it is not possible to reach each point of interaction with the MBL dashboard. So I suggest to make a user interface (dashboard), which can be used without a mouse and only with a keyboard.
