That is a good suggestion, Mattylad. Thank you for helping me. Another jumper, there, would be a good thing.
I forgot to highlight the ground plane. It makes a clear path, outside of the chip. It services the Buttons and LED. The ground on those components is not critical to the continuous operations of the circuit.
I have reworked the layout so many times that making more changes does not sound like any fun, so I think I will build/test it, as is, and add your jumper, if needed.
