dashboard – ¿Cómo puedo cambiar la apariencia del tablero?

Pregunta:

Cualquiera puede reconocer el backend actual de WordPress, pero yo no quiero eso. Quiero cambiarlo usando mi propio diseño y quiero tener una experiencia de navegación perfecta para mis usuarios. ¿Cómo puedo cambiar la apariencia del tablero? Busqué en Google muchas publicaciones y preguntas, y parece que solo puedes cambiar el CSS de la mayoría de las cosas y algunas personas estaban usando ganchos para agregar su propio código y otras cosas.

Respuesta:

Utilizo un archivo de inclusión personalizado que creé para modificar el tablero. Algunos de los ganchos y filtros están comentados de forma predeterminada, pero la mayoría de las cosas están aquí para eliminar menús, cambiar logotipos de wp, eliminar metacajas, eliminar widgets del tablero, etc.
