I don't really want/need to use a new horizontal tab paradigm that supports thousands of tabs. I just want a really good implementation of the standard top-of-the-window tab bar.

*Vertical

I was lured in initially by the novelty. But it has become an amazing tool for organizing myself. When I browse HN, I shift-click on everything interesting, and it automatically gets organized into a nice collapsible tree.

When I am working on a project, I move search results, project pages, and relevant info to a single tree.

I leave other things open indefinitely, which effectively replaces bookmarks.

Wow - I love to browse the web like that, and that functionality sounds amazing. I’ll have to try it out - thanks!
