Ok the icon set’s are not new, but they were started as gnome icon set’s and now theyfit’s perfect the KDE desktop. So remove breeze-icons and install the two awesome icon set’s
LaCapitaine (most downloaded icon set in the kde store) Papirus iconboth icon set’s are available with system settings -> Icons -> Get new Theme. The icon sets are well maintained and the designers are very welcome in help and KDE support. Thanks a lot. Don’t forget tovote in the store.
I know breeze icon awesome but we have users with different taste so eat what you like not what you get. If somebody know an awesome icon theme and need kde support, let me know, I’m always happy if I can help. For the not monochrome icon theme fans I’m working on elementary-kde icon extension and I hope I can review oxygen.
