Toolbars Tab:
The Toolbars tab shown below allows you to check or uncheck the checkboxes so that a given toolbar is either visible or not. Note that the mainmenu bar is greyed out, this is to prevent you from locking yourself out of access to functions accidentally.
If you wish to create separators between groups of buttons in the same toolbar, then click on the button at the bottom that says "Drag to create Separators" and drag from there to the location on the main window that you want a separator to appear.
