Hi there,
First of all I want to congratulate you on the amazing work and progress that was made with the builders! Really incredible to work with.
I ran into a small issue in beta2 where sliders set to marquee and the following configuration:
The slides are very basic and contain images. Even though wrap is set to ‘carousel’, once the slider gets around the end of the available slides it slows down, reverses the other way a bit, and then creeps in the right direction again before running into the same issue. The movement speed is also inconsistent at times.
