If you think this is taking too much of your screen space, you can customize it in many ways.
Option 1:
Completely hide the Diigo toolbar (go to View >> Toolbars) and only use the context menu and content selection menu.
Option 2:
Merge the Diigo toolbar with another toolbar. For example, Go to View >> Toolbars >> Customize, and then drag the bookmark toolbar items onto the Diigo toolbar, and then hide the bookmark toolbar. See below.
In fact, you can save more screen space by removing the built-in search box and merge the rest of the navigation bar to the top bar, and then hide the navigation bar, resulting in the following set-up that is extremely compact and handy
Option 3:
You can also drag any of the buttons on the Diigo toolbar and move them to other bars and then hide the Diigo toolbar itself. In the screenshot below, the Diigo button is moved to the top bar, and the Diigo toolbar itself is hidden
