Code Bubbles is a front end to Eclipse designed to simplify programming by making it easy for the programmer to define and use working sets. It provides compact function-based views of the code (all backed by the underlying files) that are displayed in bubbles and that are easily moved around and manipulated on the screen. The bubbles are fully editable. A large bubble area lets the programmer set up different working sets simultaneously and easily move between them.
