Visiting a Patreon page you can see lists of free and "locked" posts with a special picture overlay saying sth like "Unlock this post by becoming a patron" – if you click on the pic, then you can subscribe to this special patreon powered artist.
I would like to see this in Membership 2 Pro – so in a list of posts
(1) all posts show up (free and "member only" ones) and
(2) the featured picture of all "members only" posts are hidden and cannot be seen by visitors (but by logged in members) and
(3) on the picture or nearby is a link, where a visitor can subscribe.
Maybe that is already possible – but I could not find any hints how to do this.
