I don’t know about you but I do most of my PHP editing in notepad or textpad. Some people prefer using the WordPress editor to make changes to their code. It has gotten a lot better recently but is not perfect. Coditor for WordPress can change that. Instead of extending the default editor, Coditor provides you with a new interface to change plugins or themes
Coditor comes with a Monokai theme. It is easy on the eye and has code highlighting, so you can make sense of things easier. This editor lets you open theme and plugin folders and make changes to any file you wish. It also has built-in code search functionality. You can download Coditor for free.
