IDE and support for CI

Give Codelobster a look. It's an actual desktop executable application, so it's a little snappier than Netbeans and other Java-based IDEs. There's a free version, but you have to get the pro version for the CI plugin. http://codelobster.com/codeigniter.html

Hey, don't work without a PHP debugger. Several free IDEs have this features built in. Two are NetBeans and CodeLobster. Without a debugger, it's like you're driving with a blindfold on -- you are going to crash!
