Jon Jackson has written up a review of the PHP Designer IDE for the PHPBuilder.com site today. In it he mentions the look and feel of the application and certain features he really enjoys.
This IDE provides you with the ability to create and manage all of the code that makes up your website or web-based software in one environment. As a rookie web developer, the software I use plays a major part in how long it takes me to do anything web-related. This means that even when I find something that works for me, I am reluctant to migrate my work habits to new software just because it's new and shiny!
At the recommendation of a friend, he tried out PHP Designer and liked what he saw. The interface is clean and professional without being overly cluttered, comes with several useful features - like Tidy and Text Highlighting - and several more. You can find out more about the software on his page on the MPSoftware website.
