That's a neat and quick demo. Although for aiming I often use a target helper and point-at modifier instead of those quick tools on the lights themselves.

I know they're not specific to the spotlight, but you could also have shown the lighting mode settings for the stage's interactive renderer (which makes composing dramatic lighting a little easier with a real-time preview) and a little bit of the things on the effects tab which affect spotlights.
