Chrome: Bookmarks are pretty handy by themselves, but if you’d like to remember why you saved a particular page, Latis can help by letting you drag specific snippets to the a bookmark sidebar.
The extension allows you to highlight specific portions of a web page and drag them to the side bar. These then function as “visual bookmarks” that you can use to jump back to that page. You can also stack related pages together. It’s not a full replacement for a proper note taking service like Evernote, but as a bookmark service, it’s a fine improvement.
