I know Mixpanel is super useful for measuring specific actions, flows and features within a webapp that you want to measure and promote, but does it have utility beyond this use case? How are you guys using it?

Were I working on a webapp at my current startup, it would certainly be my first choice as an analytics tool of the ones I'm familiar with. However, I'm not working on a webapp. Instead I'm working on a javascript library/framework that developers will integrate into their own products once it is released, I'm not sure whether mixpanel provides value to me except by proxy if/when our customers use mixpanel themselves and share some of their insights with me.
