Feature Idea (one per thread):
Hello everyone,
First of all thank you all in prismic team 
I really enjoy using your tool.
Feature idea:
Expand https://{{repo}}.prismic.io/graphql tool with graphiql-explorer plugin
Issue that it solves:
This will improve query writing speed, readability.
For people who are using graphQL for first time this helps eliminate learning curve.
Sorry for gramma and sentence structure.
Hi Arnas,
As @marcellothearcane said there is already a graphiql explorer available, if you are visiting https://your-repo-name.prismic.io/graphql and getting a 404, this means graphql isn't activated on the repo.
If anyone needs this activated you can do so by following the process described here:
@marcellothearcane and @Phil Thanks for fast response.
@Phil graphlQL is working perfectly in my repo. Thank you 
@marcellothearcane you are right about explorer and autofill.
Using this approach I found myself going deep into docs section, to find which fields are available and where is data which I need is laying. Which is fine, but using prismic + gatsby on another project I just felt in love this feature, and I really missing it in official prismic graphiQL api.
I understand that this is paid feature and this may not be a high priority. But as a developer I found it very handy.
Thank you guys for you time 
I was going to suggest https://graphiql-online.com/graphiql, but it doesn't work without POST on the endpoint (Prismic uses GET instead).
