Testimonial Slider

Hi, I am using this theme on several of my sites successfully. On https://www.mattfurness.co.uk/session-drummer/ I am using a TP plugin to display testimonials as a slider. However the support for this plugin is no longer good and I would like to use a feature provided by Catch Themes. As far as I can see this theme does not offer a testimonial slider like, for example, Catch Fullscreen Pro. I can use Essential Content Types plugin, but as far as I can see this only offers a static testimonial display. Am I correct? I also have Catch Slider Pro which might give me what I need. The bottom line is that I want to have a display similar to that already there using Catch, without changing the theme. So, can you advise me on my best option please? Alternatively can you add the Testimonial Slider feature to Rock Star Pro to bring it in line with other themes, as that would make it easy for me! Look forward to hearing from you. Regards, chris
