I understand that if I have the ink in a pen, it shows as used, and daily usage shows how many days I have clicked on it as used on the currently inked page, but what does usage show? Is it maybe refills?
And what happens if I use another ink in that pen? Does the information about the usage of the previous ink go away or reset? Or does it still show usage and daily usage even if it is no longer being used?
I hope that makes sense!
