Visual header settings - hide icons for developer view when set

With the new option feature called 'Use modern visual header with update styling options' the developer can customise the visual header icons that are displayed for any objects in a report. This only affects the end user (published report). I would like the developer to see this same view when building the report. It is frustrating to have to republish a report if I have misconfigured one of the visuals. I would prefer a WYSIWYG approach to these icon settings. It has to be easy for the developer to see the settings they have used. At the moment it is a tedious process to check all visuals property by property.
