Gnome 353 has gained and a new Disk Usage Analyzer but is not considered as something to highlight. Minor changes mostly in design. What is more anticipated is the upcoming Usage Gnome App which is pushed (I guess) for the release after 360.
Also I discovered an extra view in Power Statistics that shows the AC Adapter.
 The new Disk Usage Analyzer first screen
 You can scan remote Disks
 The treemap chart and a permission denied notice
 And the ring chart view, as well as the usual from now on Application Menu
 This is the new Power Statistics App where a new AC Adapter tab has been added
353 release seems very boring, the only exciting thing (talking always about interfaces) so far was Empathy. All Gnome Apps had more or less a re-design and are more beautiful; but nothing really special.
