Customizing the User Interface, Part 1
-

Let’s start with the basics here with something you might not know or may not even have heard of. First let’s learn how to remove buttons from toolbars. Right-click on the button or any other element you want to remove and choose Customize -> Remove from Toolbar. The item will be gone now. If you want it all back you can repeat the process again except selecting “Reset Toolbar to Its Defaults” instead.
-

Go to Tools -> Appearance (or press Shift+Opt+F12 on Mac / Shift+Alt+F12 on Windows or Linux).
-

Choose the Buttons tab at the top. You’ll see lots of different interface elements available for you to choose from. Don’t be afraid to explore by your own.
-

Let’s add some space to the address panel after we’ve cleaned it up from the elements we don’t use. Select “Spacers” on the left and drag the Fixed spacer item from the right panel in the very beginning of the address panel until you see the insertion marker and then release. You can drag items from the Appearance dialog box to lots of different panels and toolbars inside Opera, not only the address bar.
-

You can also move items without opening the Appearance dialog box. Simply hold down the Shift key and then click and drag any element to its new position. Now when you know the basics, go ahead, play around! More customization tips to come :) Have fun!
