Consistent usage of tabs in applications

Many applications use "tab" interfaces to handle multiple documents in a single window. Examples are Firefox, Gnome Terminal, Konsole, Gnumeric, OpenOffice, Gaim. Each of these, however, use a slightly different presentation of the tabs (top of page vs bottom of page, close icon on tab vs close icon on right of tab bar, keystrokes for new tab, keystrokes for close tab, keystrokes for moving tabs and switching between them). This specification describes the process of making all of that consistent, app by app. The goal is to replicate the Firefox 1.5 interface as widely as possible.
