What do you not like about Firefox's Tree Style Tabs? I might be open to an alternative.

I Cant't hide the tab bar without some userProfile.css hacks, while in Zen it has first class support.

It's more a matter of saving precious vertical space.

I see. Yes, I already hid the stock tab bar years ago and forgot about it.
