.nifti_plotter() widget "value at point" output

[DanNBullock]

The gif presented in the readme.md file depicting volumetric image plotting features a "value at point" output behavior that appears to print out the value at the specified voxel.

However, this does not appear to be a default behavior of the current version of the widget. Furthermore, a GitHub search of the repo for "value at point" does not return any hits. Is there a hidden option for this behavior? Has this functionality been removed?
