Social

Behavior is not based on the individual alone, but it stems from the people around you. Suggestions for Stacks or even Bubbles can be generated based on your friends, family and others similar to you. They may even be shared amongst this group like a “mixed tape” of suggested websites.

Multi-user

Often times a family shares a computer and thus an operating system. Not every individual using the same machine will share the same set of tasks or the same desire for information. Providing the ability to provide different versions of Bubble Stacks dependent on a given user is a logical iteration of design.

Bubbles and Time

Currently the design best supports time within the History view. The Stacks view represents time on a smaller level by basing the unpinned areas on popularity (a factor of time). Bubbles remove the concept of time altogether. One future concept looks at the ability to bring an element of time into the realm of Bubbles.
