I just installed SP4 , and now I've got this great option, Clear All Top Level Overrides. Beautiful. Love it. Really.

I'm just wondering how it is different from the Remove All Component Appearances option. This is available if you left click in the Display Pane of a part that has a component color applied in an assembly. Remove All Components is also available in SP 3, but Clear All seems to only be available in SP 4. Just curious about what the difference is. Anyone?
