Output / model response window

[adamdbrw]

We should see results of execution in a dedicated space. This needs UX design:

• Sometimes, a response is needed.
• Sometimes, it is iterating with the API and human can oversee.
• Sometimes, something goes wrong and we need to intervene.
• There should be an Restore / Undo button (for UX).

I removed the priority/critical label, as the basic functionality is implemented now.
