Hello,
As you can see there is 2000+ active install of this plugin in around 3 months. In the document we have defined how to create a slider. Plugin is created with WordPress custom post type so it work same like WordPress post section to create a slider.
People who are spending $6 OR $9 dollar, first using the free version and then going for Pro and we have 100+ sale of this plugin in 1 month.
In the Pro version we have just added the more designs with some more shortcode parameters BUT the format is same like Free version.
Thanks for your rating and review.
