Alas the systray icon looks like a stranger in my KDE SC environment. It seems to be smaller than the other systray icons (the icons in the KDE SC tray are in size 24, the quiterss icons seems to be 16 or 22?) and it doesn't match the style/color of the other systray icons. It would be great if it would be possible to change the icon via an SVG image in a KDE plasma theme. If no KDE SC is used and/or if no quiterss.svg/svgz is available in the icons section of the theme the tray icon should use your default icon. But if a quiterss.svg/svgz is availabe in the current KDE SC plasma theme then that one should be used.
