closing a "nested" window with a button in PySimpleGUI and repeating this process

[Serafim]

From every example I've seen I think the "Simple" in PySimpleGUI refers to the design of the package instead of it's use.

If I compare my GUI programs over the years, PySimpleGUI is the one that gave me the most GUI-functionality by the smallest amount of code. It is not the most versatile but good enough for many cases. So it might refer both to the design and the ease of use. I used it in my two latest projects and it was actually pretty easy (after some reading before starting the first project) to get the GUIs up and running. For my next project I will have to find something else as I want to do things PySimpleGUI cannot deliver.
