If you think we need to support another command, you can either make an issue requesting support, or just implement it yourself.
Adding new commands is easy. In lib/index.ts, you'll see the
implementation of our current commands. If your command is already supported by
wd, you should be able to get all the
information you need from webdriverio. Make sure to add tests
in spec/index_spec.ts, and run npm test before you
submit.
