hey @toddself I did nearly the same thing in my other PR. I also want to export a few more helpful interaction classes, so do you mind if i close this one in favor of #254 ?

[themadcreator]

Well I merged the other one, so closing this one.

@themadcreator that sounds fine with me :). what ever gets the interface published works!
