What custom Nova packages have you built?

We have built private Nova packages for clients covering: signature capture fields, geolocation pickers, advanced JSON editors with schema validation, multi-tenant scoping middleware, Stripe Connect payout tools, Bagisto product catalog bridges, audit log viewers with cryptographic verification, CSV import wizards with column mapping, and webhook debuggers. Most of these are private to the clients they were built for, but the pattern is the same: clean Nova package structure, Vue components when needed, Pest tests covering the PHP layer, and Storybook documentation for custom Vue components.
