Still missing part is now I think the front light only when I do not forget anything. Maybe I get a really cheap one (the cheap Herrmans I have on the cargo Surly is totally fine), or some used fancy like a SON would be great.
I've had all sorts, from fancy to none, and frankly, the B&M Cyo has been nothing but excellent on the commuter for a few years. Can't fault it to be honest.
That mudguard fitting is delicious.
