the 2nd panel is wasting place in height

[Jérôme Bouat]

Hello,

The default 2nd panel is wasting place in height especially on small 
screens.

The new 13" notebooks have a DVD writer as well as a powerfull processor 
and thus need a Ubuntu desktop version instead of the netbook version.

Moreover, the new displays are mostly with a 16/10 or 16/9 aspect ratio.

Thus I think that having a uniq panel would save place in height and 
make the end user life easier.

Regards.
