@headlessNode Sorry, my fault. I think this PR needs to be redone, but on the latest changes to develop. I made some updates to expand-dimensions earlier without first merging this PR.

[kgryte]

Looking at the changes, it should be straightforward to apply to the latest develop, as I had also updated examples, so the PR shouldn't require as many changes.

May be easier to simply close this PR and open another, while using this PR as a reference.
