Thanks for the contribution! I made a couple updates around names before landing and added it to our Kotlin API.

If you have a chance, could you reach out to let us know how you/your organization use Litho? You can find my email if you search for my name in the git log for this repo! We're trying to evaluate how we want to engage with OSS and it'd be helpful to understand which other people/organizations are currently relying on it.
