I'm wondering if this has had any eyes on it or it's sitting in limbo. Happy to make any changes needed; just looking to use the functionality in one of my projects.

It would be great if this could be merged, we want to pass a bearer token in as a header.

Any chance this get's merged - It's the only reason I can't use graphql-playground over graphiql

Also could really use this for a project I'm on. Unfortunately this repo doesn't seem to be very well maintained. Last commit 28 days ago, with 33 pull requests :/

@HuVik Congrats on releasing v1.8.0! Would be great if you could publish it to npm as well, so it can be used from the jsdelivr CDN. Too eager to start using this instead of GraphiQL 😇
