Provide option for feature #4114

I found show-names feature very useful. I want to contribute someday.

What I really want is totally hide id and only show-names but it would be conflicted to show-names.

So I think it would be better if feature can provide options. ex> for show-names there could be three options. single-select option : id(user-name), user-name(id), user-name only multi-select option : in conversation, in commits, in change files....
