Where is the "Legacy" mode?

It used to be very inconvenient and frustrating to enable the “Legacy” interface for image generation every time I went to that panel and whenever I had to reload the page, which happens often, as your site regularly drains the browser of memory. The old interface was infinitely better than the new. Now the switch to “Legacy” is gone completely. Tell me you got rid of that option and everybody has to use the new interface. Tell me quickly so I can finally say goodbye to your popup-bombing, censored website.
