Can't customize mail's compose toolbar
I think I used to be able to customize the toolbar for the compose email window with Apple's Mail program.
Seems in mountain lion that when I bring up a new compose window and then go to the View menu, that the customize option is greyed out. And right clicking on the toolbar doesn't give me a dropdown option.
I want to add an "add link" icon to my compose toolbar.
Does anyone have a workaround or suggestion?
thanks
