Ribbon is dynamic to your current task, using a table? Table tab is available.
So were toolbars in Microsoft Office were similarly dynamic.
They also were primarily shortcuts as everything could be reached using the menus anyway.
Ribbon contains everything that is available in the menus, and is collapsible. Ribbon also supports keyboard accelerators
They also aren't predictable.
Do you have examples of other apps with dynamic toolbars that work better?
