Emitters have emitter methods

• .on(feature, listener)
• .off(feature?, listener?)
• .once(feature, listener)
• .emit(feature, ...args)

Emitter syntax

• ux.enable.on(feature, listener)
• ux.disable.on(feature, listener)
• ux.forget.on(feature, listener)
• ux.enable.off(feature?, listener?)
• ux.disable.off(feature?, listener?)
• ux.forget.off(feature?, listener?)
• etc.

Emitter example

// Listen for when 'crazycolors' is enabled
ux.enable.on('crazycolors', function(feature) {
  document.querySelector('html').classList.add(feature)
  console.log(feature + ' enabled')
})

// Enable 'crazycolors'
ux.enable('crazycolors')

You normally would want to also listen for when the same feature is disabled and do an opposing action. You're also likely to have multiple (and maybe related) features. ux doesn't care what your features do. It only provides the API for enabling, disabling, and remembering them. Do what makes sense for your features and users :)
