and wanted to use opendoas, maybe already know that there exist opendoas-sudo in AUR for drop-in replacement (symlink doas to sudo) so you can type sudo (and programs wich use sudo) instead of doas (for convenience).
But there was still a thing like visudo missing.
So i forked vidoas (see links below) and changed it for Arch specifics. And created a drop-in replacement for it too.
