Great. It might not be possible by it’s current design, but I would join to Jon Inazio Sánchez Martínez with an idea of having an ability of keeping the slider on top of the “middle content” in collapsed state. That would make it simply perfect.

Hi thanks for the feedback - i will try to implement an option to reduce the height in collapsed mode to zero so that the trigger overlaps the middle content - please create an issue on github for disussion :)
