I want to suggest a small tweak to the design of the charger cable terminal, or head. When I plug in the present terminal on my SP4 the LED indicator light shines out to the side and requires me to crane my head slightly to check if its on. I'm suggesting that when the time comes to consider remodelling the charging cable, they replace the single LED on the terminal head with two smaller ones set diametrically opposite each other, such that, regardless of which way users plug in the terminal head they will always see a tiny pin-prick of light shining directly at them whilst working at the screen.
