Nice tool, the Prism integration looks really nice.

Some feedback:

- The left hand menu for API, versions, documentation (or something) totally confuses me. Even after thinking about it for multiple minutes I don't really get it. I think there are multiple things being represented by the same interface type, but I'm not sure.

- Sometimes action buttons on top, action buttons on the bottom.

- Prism... where is it? Why does the main interface change when I switch from "hosted" to "local"? What does "local" actually mean?

You have a really nice tool, but for now it was too complicated for me :/ Some UI and usability love would probably help quite a lot.
