HOLA A TODOS:

A ver que les parece esto que les tiro.

Es un editor que al recibir el foco cambia de color y la apariencia de la fuente y cuando lo pierde (al foco ) vuelve a la normalidad.

En realidad me hacia falta algo asi y comence a diseñarlo; seguramente esta para arreglarlo y mejorarlo pero a mi me sirvio a pesar de sus defectos.

Perdonen por no haberlo comentado, me parecio que no hacia falta.
