Bookmarks Sidebar is a Google Chrome browser extension that allows you to access and manage your bookmarks by clicking on the left side of your screen. The sidebar can also be set to auto appear when you move the mouse pointer to the left side of the screen; AND, if you don’t want it on the left side of the screen you can change it to the right side. There are other configurable settings, as well.
After messing around with this extension for a while now; especially, on my Chromebook, I have found this extension to be one that I cannot live without. This is something that should already be built into Chrome. I love the idea that I am now making full (easily accessible) use of my bookmarks and have found that I am now organizing my bookmarks more.
If you use Google Chrome, I highly recommend this extension. Highly rated in the Google Chrome Store
