Is it possible to reserve the membership plugin for access only by super admin? I'd like to use the membership plugin for my main site, but it is accessible to all sites. If I network disable it, I cannot use it on my main site. It's not so much that I don't want my sites to have it as much as it is featured in admin and looks intimidating. Is there a way to hide the membership from the admin dashboard so it doesn't jump out at my sellers?
