Awesome, really glad to hear you’re love it ?? Means a lot!
Regarding your questions:
1) Yes, you should be able to do this by simply drag-and-dropping the slides in the “Edit Slideshow” panel. Is it not working?
2) Do you mean make the slideshow responsive? If so, there is an option for this under the “width” and “height” settings in the “Dimensions” box. It’s allow the slideshow to scale down/up proportionally with your theme.
3) Captions are a “Pro” feature. Documentation can be found here.
4) Yes, best to have “Lite” disabled when “Pro” is active. No real need to have both activated ??
5) Not natively, but it’s a feature we’re going to add soon. In the meantime, you can implement it manually. Have a look at this support topic.
Hope that answers your questions. Feel free to ask more if you have any ??
