The Control Manager in System 7 (and earlier) was pretty barebones in terms of features. Buttons, checkboxes, radio buttons, scroll bars, popup menus, and text fields -- and that was it. A lot of commonly used UI elements, like heavy lines around default buttons or boxes around groups of controls, weren't part of the Control Manager and had to be implemented by individual applications -- and anything more complex like tables or toolbars was right out. The System 7 version of Control Manager didn't apply much in the way of styling to controls, either. Windows were white; controls were black and white. Scrollbars got a bit of color in System 7, but nothing else did. It was funtional, but it wasn't pretty, and a lot of applications used custom CDEFs to add a bit of shading and color.
