TreeBrowse was a small project at first to have something better than a one-dimensional browse history (back, forward). By building a tree-structure as you browse through pages (and surf the web), you have a better view of how you got to where you are.
And there's more. On summary pages with links, you see a number of things you want to read, but when done with the first, you can't find the other any more. Press the links whil holding Ctrl, and nodes are added to the tree for later. Then view the items at you own pace. To clarify the overview, mark nodes with different icons, or drag and drop them to other places in the tree.
