To make scene components easier to spot,

I added a billboard component, but I keep forgetting that when I click on it, the billboard component is selected, not the scene component. Is there a way to visually indicate the location of a scene component (Destination)?

Instead of using an empty scene comp, you could use an arrow component for the Destination marker. That’s how I set up the entry points for my vehicles and furniture. As an added bonus, it will also show the relative/local rotation of the marker, which is helpful if you grab its full transform to have something match the rotation when it reaches destination (arrow will give you a preview of where user will be facing).
