Auto Fetch Flake Inputs

[cloudyparts]

I see this across all my Nix repositories but cannot find the configuration setting in the docs or plugin codebase.

Can you provide a full list of all configuration settings in the documentation?

.vscode/settings.json

{
  "nix.enableLanguageServer": true,
  "nix.serverPath": "nil",
  "nix.formatterPath": "nixpkgs-fmt",
  "nix.serverSettings": {
    "nil": {
      "diagnostics": {
        "ignored": [
          "unused_binding",
          "unused_with"
        ]
      },
      "formatting": {
        "command": [
          "nixpkgs-fmt"
        ]
      }
    }
  }
}
