> MO we should ditch tabs, bookmarks and history. They all implement the same thing - a way to reach a place you've visited before. And they all require to be micromanaged in specific ways. The browser already knows which sites I've visited recently, and all the backtracking and branching I did. This information could be visualized as tree so that I can backtrack to any node and resume browsing on a new branch. The browser should also be doing memory management so that revisiting recent site is as fast as switching to another tab. And while we are at it, why not allow full text search across recently visited sites?

Yes! This! Essentially, something like Emacs's undo-tree, but representing the tree in a more compact form, using some variant of D3 or Graphviz's tree layout algorithm.
