In the bottom pane, we have the option to do display JSON pretty printed. It would be better if there was also an option to expand and collapse each level of the object hierarchy, making it convenient to drill down to properties nested deeply within the JSON object. Also, a search box above the pane, so you could search within a specific log entry.

Thanks for the feedback Brad.

When we implement this feature, we will definitely be adding a new custom extension type which would allow users to write their own viewer.  Unfortunately, we have a backlog of ideas at the moment, so I am not sure when we will be able to implement this.  It is a big feature with usability and performance implications which needs some more thought so that it is a clear value add for all users.
