Prolific KDE developer Pawan Yadav has updated the PotenzaRemix theme bringing it to version 1.7. The theme, as he explains, is a mix of Potenza and Awoken (action icon) with his custom icons.
If you are already running the previous version of this theme and want to update, he suggests deleting the previous theme from the usr/share/icon folder.
If you are installing it for the first time, just go to System Settings > Icons and then click on Get New Themes. Here search for the potenzaremix and install it.
KDE gives a user complete control over his system and makes it extremely easy to install new desktop themes, icons and color schemes.
