Hi, I would like to propose to use the Papirus open source icon theme for Linux (https://github.com/PapirusDevelopmentTeam/papirus-icon-theme) as default icon theme for the different DEs to give a consistent look to new users (when there will be some...). I use it myself and it is the only icon theme so far which is consistent in XFCE4 and KDE which I use both and therefore I hope it will have good chances to be consistent also in other DEs. Hints, improvements, critics are welcome.
