Comment 111 for bug 386150

@Marcus: sure, no problem...

I'v been using your ppa in Karmic, and my observations:

1: I Find the lack of the "Up" Button crippling.
I would even suggest replacing the "Home" button with the "Up" button.
But I have realized there is more space wasted due to the 2 drop down buttons.
We could remove one drop down button and reduce its size , This is allows us to Add the "Up" button without compromising the space.
The single button can function like firefox's drop down menu.

I'v attached a mockup of the idea...

2: You might already be aware of this, but just to bring to your attention.
The Appearance Preferences > Interface > Toolbar Button labels option has no effect.
