User reviews

Até hoje usava o Code Injector que irá ser barrado pela Google. Felizmente descobri esta Extensão ! Sou fã ! Funciona muito bem com o Jquery, e é "user friendly". Parabéns ao criador !

Rate 5 stars. BUT! How to close JS editor if I want to use only CSS editor? Как отключить/свернуть JS панель когда я ею вообще не пользуюсь?
