But where are the lighting controls in the new version?

Sorry guys but it feels like moving furniture round for the sake of it, what is actually beneficial here? Time could have been better spent improving the controls, particularly the three select, reseize and rotate tools into one tool, allowing resize from an edge instead of from centre etc.

OK I worked out its in ambience in the scene panel. But I cannot work out how to get to the HDRI backdrop adjustments. Sigh.

Under Ambience click on Env. HDRI Environment is towards the bottom of the panel. Select details in the HDRI Enviroment Panel for additional settings.
