Working On An Offline Collection

Hi everyone,

Because I don't want my collection data stored in a third-party cloud or tied to a monthly subscription, I started building a lightweight, 100% offline Windows desktop application (stores everything locally on your own PC in a private database).

Question for you.

1. What specific fields or details are an absolute "must-have" for you when cataloging an item?
2. For those who have insured their collection: what information did your insurance company require in your documentation report?
3. Looking at the screenshot, is there anything you would change or add to make daily cataloging faster?

Thanks in advance for any thoughts or suggestions!
