Papirus is our favourite Linux icon set, and it has just scored another big update.
The October release includes icons for 0ad, Open Arena, Sound Juicer, Hamster, Harmony music player, Streamtuner, Skype for Linux Alpha, and a fair few more besides!
There’s also updated applet icons for KDE (yup, there’s a version of this theme available for KDE) plus ‘recoloured panel icons for GTK’, and other miscellaneous improvements, symlink fixes and more. It also supports hardcoded tray icons.
If you’re running Ubuntu 16.10 you can download an installer from the Papirus PPA.
