Yes it isn’t and probably won’t be! 😉
How do you know the plugin is great since you never used the feature that makes it great?
Just have to make in your theme folder another folder called: flexible-posts-widget and copy inside it the widget.php from the plugin folder called views. Then asuming you know the copy/paste edit that widget.php to your liking: put the wp-hook to output that date, the wp-hook to output the post comments maybe …etc.
