No, that is not currently a feature, although it could be implemented.
Okay, I will try to implement it, most likely as an option for LocalSettings or as something via CSS.
You should be able to follow the pattern of other preferences in the extension to add it as an option.
Yes, of course.
However, just in case that you find it easy for you, I would be prefer you code that, I help and document it.
