During the latest SLN all hands the team gave some insights into game lenses that caught my eye:

Having the user's front camera visible with picture in picture lead to higher engagement on spotlight. Versus focusing entirely on the game lead to higher retention, and greater shareability between friends.

As lenses become more and more complex, it would be great to have more insight into what makes our lenses engaging. Having a A/B testing suite would go a long way for optimization.

Give us the ability able to swap out or toggle certain components, and see which variant gives the most engagement/shares/views/playtime etc. with a reporting platform or dashboard in my lenses.
