Fails since WP 6.4.5 – developer closed?

I loved this. It was exactly what I wanted. Sadly, it hasn’t been updated to be compatible with recent updates to WP and nobody from the development team appears ever to respond to the free support forum. The Plugin’s own website appears to be inaccessible (so I can’t contact them), suggesting to me that this is not going to be updated. I’d be happy to be corrected, but the plugin’s failures to hide certain menu options on my sites mean I am now having to completely re-think how to approach this. My advice would be not to install (free or pro).
