Feature Request: Add support for structured key-value secret collections

Hello Bitwarden team,

I’d like to propose adding a new item type: structured key-value collections for storing grouped secrets, similar to formats like .env, TOML, or INI.

These formats are widely used to store configuration values in plaintext files as simple key-value pairs. Currently, Bitwarden can approximate this via secure notes or custom fields, but these approaches are limited for real-world development and DevOps use cases.

Native support for key-value collections would:

  • Provide a clean and structured way to store multiple related secrets in one item
  • Improve usability for developers working with environment/config values
  • Enable better API/CLI automation
  • Allow optional import/export of simple .env-style or INI-style text blocks

Supporting this would make Bitwarden a more attractive option compared to dedicated secrets managers (like Doppler, Vault, or 1Password Secrets Automation), and help bring more developers into the Bitwarden ecosystem.

Thanks for considering this feature!
