The show tools are located on the right side when you are in "Show" view, with a show selected. Here is a list describing all the tools:
Here you will find all of the current groups in the current show, and a list of all your global groups. Click or drag them to the center to add them to the current layout.
Change the order of slides (Can be done in the center too). Add transitions to each slide, set next slide timers and loop to beginning.
See all of the media layers in all of the layouts. This includes all of the backgrounds, audio and MIDI actions.
Set metadata like title, artist and CCLI data about the current song. This can be enabled to display under the output settings.
