A core goal of the CommandBar Editor is to make it easy for you and your team (technical and non-technical folks alike) to understand why your CommandBar is behaving in a certain way, so you can create finely tuned experiences for your users without tracing through code.
We launched the Debugger several months ago to allow anyone with Editor access to understand what SDK calls were being made and contributing to CommandBar's behavior. Today we're launching several improvements to the Debugger experience, including a fresh new UI that makes it easier to quickly assess what SDK calls are being made in a given session and double click into the body of the SDK call.
