Is there research results which quantity whether Golden Ratio is good for window management?

Try it and see?

If you can't see the code in a window, why display it at all?

I can't see how the golden ratio is useful in making a window the "perfect size"...

The golden ratio is a terrible window ratio for editing.

Why is that?

I'm not the parent, but the linked project has some bold statements in its README:

> each window has a size that is not convenient for editing

> The window that has the main focus will have the perfect size for editing

and nothing to backup these claims except a wikipedia article that, in fact, doesn't.

The parent's comment goes well with the project's claims, I'd say.

Time to pull this one out again, Fibonacci Flim-Flam:

My own experience with editing windows is that I'll need different dimensions for different tasks. While a vim-plugin or such that did dynamic pane resizing might be useful I don't think the fundamentally aesthetic concern behind the golden-ratio cult adds anything to this.

I didn't really need to be convinced as I have a profound aversion for pseudo-science but that was a very interesting read. Thank you.

Once the window's wide enough to display full lines of text, you only benefit from having more rows.
