“Unity Interface has just received a massive overhaul
in Ubuntu 11.10 and the main dash menu looks better than ever.
Application access and discovery has improved greatly. Two main
lenses in Unity launcher, Applications and Files Lenses have been
removed and are now integrated into the dash only. A new Music Lens
has also been introduced for quickly searching and browsing your
favorite artists.The Ubuntu Button on top left corner has been removed and a new
big Ubuntu orb on the launcher now activates the main dash menu.
Active blur option for the dash is turned on by default now giving
it a really sleek and polished look. Application title, window
controls and app menu on top panel now show all the way to the
left. There are still two more Betas to come so the interface will
be polished more overtime as it is quite slow and there are still
many rough edges.
