OLED Saver
This is a KDE plasmoid widget designed for OLED monitors to minimize burn-in retention caused by constantly displaying the same icons on the taskbar. By changing the widget width at set intervals, the entire panel will be shifted by a random distance.
For best results, install the "Breeze Black" theme (to make the taskbar completely black), set your wallpaper color to black, and then add two identical widgets on either side of the taskbar.
