Not the OP, but for me the big pain points with Postman are
* Sync-ing with an OpenAPI spec is one-and-done. If new stuff is added to the spec, you have to start a new collection and throw away all your existing work (or in practise add the new APIs by hand)
* Many times I need to execute a sequence of requests to do anything useful. For example, I might need to get a list of objects, scan the list and pick the one i want to interact with, take the ID, copy-paste it to a different request, etc. Some requests I want to interact with I might need to grab 3 or more IDs from different endpoints. It's possible to improve this somewhat with Postman collections but I've always found them to be a lot of effort to set up, flaky, and cumbersome.
Next time I reach for Postman I will give this a go but it's not clear from the demo video if/how it addresses either of these problems.
