The ability to see the generated JSON is very useful. When I look for problems, it is very quick to find issues by looking at the generated JSON. Also, when I want to compare 2 objects to understand why they behave differently, viewing the generated JSON is key.
If I understand you correctly, I will still be able to see generated JSON at the top levels... But when I have nested panels it will become much harder to find generated JSON for a specific component.
I believe that your proposed change will make the tool much harder to use. Please consider providing a way to get to it (even if it is only for advanced users).
I cannot recreate these issues in a new / smaller project. My assumption is that my project got semi-corrupted with all the upgrades... even though it mostly works, I have to restart designer quite frequently (every few minutes).
Is there a way for me to privately provide you a copy of the project and know that it will stay confidential?
