You've configured your printer, barcode scanner, tax rates, and number formats. Then an update rolls out and suddenly your scanner doesn't work, your invoice numbers reset, or your preferences are gone. It's not just annoying; it's lost productivity and trust.

Stable software treats your settings as sacred. Updates add features and fix bugs without overwriting your config. That requires discipline on the developer's side: separate app code from user data, test upgrades on real configs, and avoid "reset to default" as a lazy fix. As a user, you can't always see that from the outside, but you can look at reviews and release notes. Do people complain about resets after updates? Does the vendor mention "settings preserved" or "seamless upgrades"?

You're not just buying features. You're buying something that won't undo your work on a random Tuesday.
