These days, I’ve heard a lot of arguments about the new design of the window control of Ubuntu 10.04 Lucid.Some people like buttons on the left, and some like the right side.I think the important thing is: how user can change it.So that’s what Ubuntu Tweak does.
Canonical is burying Ubuntu's traditional brown theme and is adopting a new visual style for version 10.04, which is scheduled for release in April. The new theme was revealed last week as part of Canonical's broader effort to overhaul Ubuntu's branding and visual identity.
Some time back we have posted about Deconstructing Nautilus and rebuilding it better and now you can see small video on this
The new style of Ubuntu is driven by the theme "Light". We've developed a comprehensive set of visual guidelines and treatments that reflect that style, and are updating key assets like the logo accordingly. The new theme takes effect in 10.04 LTS and will define our look and feel for several years.
