If you like to store your favorite bookmarks on the Safari Bookmarks bar for one-click easy access but you've run out of space then ButtonBar+ is the extension for you. With ButtonBar+ you can create a second bookmarks bar for Safari that is highly customizable and configurable. What's more, you can create additional instances of the Bar - it's like having as many one-click bookmarks bars as you wish.
