New issue 1105: [experimental] make subpage in docs for TransferFunctionHelper https://bitbucket.org/yt_analysis/yt/issues/1105/experimental-make-subpage-i... Cameron Hummels: in the VR docs, TransferFunctionHelper has a very useful long notebook demonstrating how to use it. unfortunately, it's right in the middle of the narrative docs, and it really breaks up progression of the description of using VR. I think it should be split out into a different page in the narrative docs and linked there as well from the cookbook/notebooks page.
