Hey. Just a question. Can we add possibility to extend from single string not just from array? So it will work like other linting libraries (eslint, stylelint, etc.).

package.json

"babel":  {
  "extends": "shared-tools"
},
"commitlint": {
  "extends": [
    "shared-tools"
  ]
},
"eslintConfig": {
  "extends": "shared-tools"
}

Use update-notifier to notify users if they're using an older version.

When I am in a github enterpise repository, e.g., https://git.<enterprise name>.com/<org>/<repo>, this bookmarklet doesn't work.
