I was thinking about encapsulating the modifier from the user in Style. So instead of:

Style::default()->addModifier(Modifier::BOLD)->addModifier(Modifier::ITALIC)

User would use:

Style::default()->bold()->italic()

To remove one of those modifiers:

Style::default()->bold()->italic(false)

Or even new methods (which isn´t my preference) like:

Style::default()->bold()->withoutItalic()
Style::default()->bold()->removeItalic()

But, I'm not sure yet ... Wdyt?
