Best practice with "no break space" (U+00A0) in code and design view? I do not talk about " "

Hi.
I'm using the latest version of Dreamweaver 21.3 on macOS.

I prefer to use the UTF-8 character "U+00A0" for the "no break space" instead of the named entity " " in the code view.

For better readability.

It is visualized by a red dot.
But a red dot is shown as well, wenn you put a standard space at the end of line.

So a red dot is not an exclusive visualization exclusively for a "no break space".

1st question
Is it possible to configure another visualization of the U+00A0 in the code view?

2nd question
In Design View the option "Show invisible elements" is selected. However, the U+00A0 is not visualized.
Is it possible to achieve this?

3rd question
With the shortcut CMD+SHIFT+Space a " " is entered in code view.
Is it possible to have "U+00A0" inserted instead?

Thanks.
