It would seem to be easy, but I’m not doing well. I need a simple/light text slider. There are four widgets in the footer of the page and one of them is supposed to be a text slider (only text). I tested https://de.wordpress.org/plugins/text-slider-testimonial/. It works well, but I don’t know:

• how to change the slide duration?
• How to indicate which slides should be shown? (I would like one slider to display slide group A and the other slider group B)
• how to hide a headline?

Besides, there is no decent manual for this plugin anywhere. It would also be useful to have a navigation option (dots). I tried to use some different “testimonials” plugins, but every time there is a problem with CSS. Each of the plugins imposes its own CSS for text, and I want to use default CSS (like everywhere on my website).
