Lubuntu is about to get a new icon theme.
Little is known about the set, called ‘Lubuntu box’, so far, however the Lubuntu team have said that it will initially only consist of ’a few icons’. From the image above I would go as far to guess that the first icons to be included will be those folders and other ‘file manager’ sidebar emblems.
A design guide is being developed to help ‘create the main look [of the] line.’
The Ubuntu-based spin currently uses a tweaked version of the elementary icon set as part of its default appearance.
