"Developers spend significant time reading and navigating code fragments spread across multiple locations. The file-based nature of contemporary IDEs makes it prohibitively difficult to create and maintain a simultaneous view of such fragments. We propose a novel user interface metaphor for code understanding and maintanence based on collections of lightweight, editable fragments called bubbles, which form concurrently visible working sets.
The essential goal of this project is to make it easier for developers to see many fragments of code (or other information) at once without having to navigate back and forth. Each of these fragments is shown in a bubble"
