If you're still using GraphiQL I urge you to try out Insomnia, their GraphQL support is fantastic. The only thing I miss is auto-completion of all fields, having to type every attribute can be tedious. Also, if you need to pass headers to authenticate, Insomnia handles that gracefully, whereas with GraphiQL you need to basically install an extension (which you will then forget to disable and YouTube will act funny).
Actually, another feature I miss in Insomnia would be query groups, mainly to change the access token in the header in one place for a specific environment.
edit: I just realised it's OSS as well, so whiny people like me can potentially contribute features they're missing https://github.com/getinsomnia/insomnia
