[Camino] [SOC] Improvements to the Camino tabbed-browsing experience

[Scott]

I just discovered this list, I hope I'm not too late...

When there are too many tabs to fit across one line on the screen, 
instead of adding a drop-down menu at the end of the tab bar, I wish 
the tabs would wrap to a second line.

Not only do I think that would be very helpful in its own right, but 
conceptually I like that the behavior would be consistent with the way 
the bookmark bar works.
