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.
Saros brings multi-writer synchronous distributed editing to the Eclipse IDE, e.g. for joint code reviews, explaining code remotely, or distributed pair programming -- all also for more than 2 participants; we call this Distributed Party Programming. It includes refined awareness functionality, text chat, and a simple distributed whiteboard/sketching facility.

It is a supplement of version control system to support software development. It helps programmers to track personal working time spending on source files, and to easily find experienced people who may help you to comprehend certain code fragment.
