I had created a new variant of Cog's user interface.
New version contains new vector toolbar icons, new high-resolution application & filetypes icons, new dock badges, new look of File Tree, some UI fixes & improvements (such as text spacing), improved appearance of Main Window, Spotlight Panel, etc.
