Beautiful. I never used the cloneElement before because I wasn't sure of it's usecase but this is an awesome way to handle it! 10/10 subbed :)

how would you go about adding arrows (css triangles) that will always stay in the center of the child component?

This is amazing but how would you use this in a table that maps over data and generates td's ?

I'm getting ./src/App.js
Attempted import error: 'Tooltip' is not exported from './Tooltip'.

Any ideas what might be causing this?
