Shortcut to scan and save handwritten correspondence

I realized I’d like a system to quickly make and consistently store copies of handwritten correspondence such as letters and cards sent to/from friends and family. So, I wrote this. It uses Data Jar and Toolbox Pro. The Data Jar value LetterWriter is a list of people’s names that I correspond with.

Curious if others have a good way of doing the same thing.
