If AMPPS could provide a Apache/NGINX selector for the http server, that would be very nice. Think "NAMPPS".
To the extent that Softaculous scripts are more particular about the PHP & database configuration(s) and less sensitive the http server, one would hope that a Apache/NGINX selector might be feasible.
If a "NGINX+MPPS" stack were to appear separate from AMPPS, this might also be OK. However, one would need compare & choose between the both stacks as a whole (instead of just choosing between which http server).
So, any "NMPPS" would need to be on par with "AMPPS".
Either an inclusive "NAMPPS" or fully capable "NMPPS" could work for me. I'm ready to switch from Apache httpd to NGINX.
