Bookmarks are a simple way to keep track of blog posts and videos for later viewing. With a single click of the mouse, you can add blog posts and videos to your list of Bookmarks! They work much like bookmarks, but are even easier to save. Plus they will be accessible from every device you use to visit the site. If you see a post that has a technique you want to try later, or a video that you don’t want to lose, you can add it to your list of Bookmarks.
