When you open a picture file (file type "PICT") with Smile, Smile opens a graphic window. You can install some buttons in a graphic window, then save it as a Smile document : the buttons will be available when you re-open the file.
A graphic window with buttons installed can be used as a nice buttons palette.
Buttons in graphic windows
The buttons which can be used in graphic windows are the same as for text windows.
The only thing different for buttons in graphic windows is that they can be moved anywhere in the window. To move a button, drag it with the Command key () pressed down.
