How Toasted?

The amount-of-toasted dial or lever on a toaster. It's not accurate enough, and should be made better. If more than one person uses the toaster, chances go up that each user will prefer a different degree of toastiness. So, I reckon the toaster should have a number based adjustment system, making it easier to accurately re-set to whatever setting it was moved from. The currently popular Light to Dark system is just too vague.
