My mockups are simple wireframe sketches of what a the Mozilla Weave website might look like. The focus of the concept is the ability to view and organize tabs, bookmarks and history across devices. On the Weave forums users were keen to have more granular control over the information Weave stores. For example, people wanted to be able to share certain bookmark folders from home to work but not others. Not sure if this is the roadmap for Weave but I think this represents a common mental model of the product.
In this concept, users are able to copy/move tabs and bookmarks between devices. They are also able to search across and within devices and filter by tags, how long the page was open, the site the website was launched from, etc. In order to show browser data across devices the visualization of data (tabs, bookmarks, history) is kept small--bookmarks are similar to what you would find in the bookmarks drop-down in Firefox now. Tabs and History represent websites with thumbnail images. I use Tree Tabs so you'll see some nesting in tabs. I also have it History as I think grouping websites by domain would be very helpful.
