I love the fact that Insomnia has had so many improvements and I already made a few runs. The Pre-request scripting feature looks great! It is also great that the errors are gone even though that wasn't really an issue for me personally. But I think the feature that I find for me to be the most useful is the API mocking feature. This can potentially increase productivity for a good x times fold, purely because a mock API can be a lot of work and if we can incorporate that with the client than it looks like that work time and allocated effort will greatly be reduced. This is also a perfect opportunity to combine that with the pre-request scripting feature. I can't wait to explore this in more detail and make a whole article about it, with the matching video to accompany it with.
