Windows:
Arrows in Scroll Bar: OnyX allows you to choose among four types of arrows in window scroll bars. Select one of these options to modify the parameters immediately and relaunch the Finder; the applications already in memory must be relaunched to show the changes.
Speed of display of sheets: This option allows you to set the speed that a window's sheet is displayed. A "sheet" is a modal dialog which is attached to a window and asks for input from the user.
