Customize Toolbar

Open the customize toolbar window to add or remove items from your toolbar.

The customize Toolbar window is where every button from this extension and others like it get placed for you to then move to your toolbar. Creating the perfect set up is always a moving target that is never quite achieved, but this will make it a little quicker to get there.
