GUI: PSD Layers plot does not plot PSD of layers

[asoplata]

In the original tutorials ( https://jonescompneurolab.github.io/hnn-tutorials/gamma/gamma ), we use the equivalent of the GUI's PSD Layers (3x1) Figure Layout template to illustrate some scientific points about the difference between the layers; see Figure 10 in that link.

However, in the current GUI, creating a PSD Layers (3x1) Figure shows layer-specific dipoles, NOT layer-specific PSDs, see below:

I have been told that this is a known issue, and was expected to be implemented before the next official release of the Tutorials, but I couldn't find any pre-existing Issues/PRs that describe it.

Agree we should do this before 0.4!
