Body

Throughout the application we now use the editor from @monaco-editor/react which is super powerful and a full integrated IDE.

It comes with its own theme and really look and feel different from the Rest of the UI.

It would be cool to rework sees so it integrates nicely with the App, similarly to the custom RenderedJsonField we had before.

As an idea this is what we had before

                          Throughout the application we now use the editor from @monaco-editor/react which is super powerful and a full integrated IDE.
                          It comes with its own theme and really look and feel different from the Rest of the UI.
                          It would be cool to rework sees so it integrates nicely with the App, similarly to the custom RenderedJsonField we had before.
