Restore YouTube Username from Handle to Custom: Display username if user has no name

[Goosegit11]

By default the script doesn't display anything if the person doesn't have a name, this is very inconvenient in comment sections, you can't know who is replying to whom, see example:

So I'd rather fallback to the username instead of just showing nothing.

I see that there is "Support for NO NAME (EXAMPLE)" in script's description, so this behavior is intended and you probably don't want to change the default to username fallback.

Then, could you please help me how I can modify the script to achieve this?
Even better would be introducing some kind of options.
