The plugin shows all posts in the index loop as expected. Past and future.
However, I cannot navigate between past and future posts in single view. I can't navigate via single view from past posts to present posts or vice versa, only within each group.
To be more specific - in single-post view, viewing the first future post, WP page nav disables "previous post", I can only go to "next post" in the future, although there are past posts. Similarly: If I'm viewing the most recent past post, WP disables "next post" page nav even when there are future posts.
I'm on the latest 2.0 The Future Is Now version
