Update Module to Drupal 9.x?????

I was wondering if you had any interest in updating this module? I've used it for YEARs and it does everything I want (thank you!!!!). It's getting time to update the major Drupal version of the pages, but I'd sure love to keep this module. It's really the only thing holding me back from jumping in.

I know you're busy and probably have moved on to other projects but I was wondering if there was a chance? I also noticed that in one of your other comments that you don't Drupal anymore. Bummer if that's still true.

I'd give some of the other modules a look, but none of them seem to have the waiting listing flexibility that your module has.

Would you consider this a paid sponsorship or something?

Thanks!!!
