Hey,

JSONView looks interesting, and something like this could be a valuable addition. However, I would prefer to include parts of this functionality, such as collapsing objects, in the main text view.

I added a new ConsoleViewDelegate protocol, and I plan to extend it in v4.3 to allow adding "plugins" in common areas of the Console. It will support extending the response view to support new response types without modifying the framework, adding custom actions to the existing response views, and more.

If you'd like to contribute and add some of these features to ConsoleViewDelegate, I'll appreciate it. In the meantime, I would recommend sticking with a fork.
