Comment 4 for bug 319152

"There is no such thing as a systray under Gnome. It's a notification area. Applications using it as a systray are abusing it and are in clear violation of the HIG. That's why we want to develop an applet."

That's why I suggested an option - I meant in addition to an applet. The problem with a gnome applet is that you can't use it easily on other DEs but a systray (for those who use it as such) option will work on all DEs which implement one.
