It's nowhere near this advanced, but in Firefox you can shift-click tabs to select multiple, and then with Right-click you can choose "Bookmark Tabs", and it'll save them as a folder. You can then right click on the folder in your bookmarks and choose "Open all Bookmarks" (which will use the current window). I think Chrome has similar capability, but I haven't played around with it. An annotated document of bookmarks would be next-level, though.
