Last month, Canonical Will Cooke said in the weekly news that the Ubuntu Desktop team is trying to integrate the default Ubuntu GNOME Shell and meet the existing standards after the system can be installed at any time to add a variety of GNOME Shell session.
Earlier today, the Ubuntu contributor Didier Roche announced the new GNOME Shell theme, based on the upcoming GNOME 3.26 desktop environment. “We are based on GNOME Shell 3.25.91 and now becomes a transparent top panel when there is an application touch.”
