The slider provides over 150 options, grouped in several panels. Inside each panel, the options are sorted again in order to make it easier to find a certain option.
When you open a panel, the options will be visible by default to offer you a quick overview of all the available options, but you can hide all of them or only certain groups if you want to make the interface cleaner. The state of the panels and inner groups will be saved when you update the slider.
These global options can be overridden by options specified for individual slides in the slide's 'Settings' panel.
