Aptana IDE.

This isn't something I do usually, but this piece of software is so good I really had no choice left to show it to you. Aptana is a robust, open source JavaScript-focused IDE for building dynamic web applications. It really defies all other software I have previously used. Of course It can handle other scripting languages as well. But if you use Javascript a lot, this is a piece of software you would not want to miss. And hey, it is cross platform and it is free!
