Profiling Tool from Juliacon 2018

I was watching this video by Jameson Nash from Juliacon 2018 where he showcases a profiling tool (starts around 6:20 in the video). I really liked what he showed you could do with it, I imagine it could be very useful in diagnosing performance issues or just understanding your own code better. Particularly the way it showed line-by-line where most of the time was spent.

He seemed to invoke it using the command InteractiveUtils.open_profile("profile-9"). I was looking in the Julia documentation on InteractiveUtils and could not find any such command.

Does anyone know if this is coming, perhaps still in the works?
