For some people this is no big deal. For me it's an unheard-of level of organisation.
@feijoa
We do the same, except we use a text file and print it out. That way, we can both add or delete things without needing a computer handy.
We redo it when it gets too messy.
@wyliecoyoteuk I've gone a bit over the top. I've got a drop-down classification (meat/veg/pre-booked/golden...) so that I can sort everything 🤓
