That was a real challenge for the AI and for me. I wonder if it would have been easier to redesign the whole extension using AI instead of trying to update it.

But well ... 4 hours of work shouldnt be overrated. Ive already spent longer on other customisations from V11 to V12. So all good thanks to AI support.

Continue to have fun with the extension - now also with V12. Whoop Whoop

But I also have some bad news. This version is no longer available for V11 or lower.
But there is one piece of good news ... support for V11 will not be lost.
