Panic Coda is my favorite all-in-one Web Development environment but, it's missing some features of dedicated application. For example, inserting a special character or if you speak french you'll need those accents on some letters but, you can't remember the name code? Panic Coda won't help you because this function is not included in the auto completing feature. That's why I created the plugin "HTMLchar" for Panic Coda, it's easy to use and very useful in those situations.
