Comment 13 for bug 524179

@Chris: 1 consistent way for all icons in the tray I can understand. But what perhaps you don't realize is that the changed behavior isn't Gnome-specific - it propagates through to other DE's, like KDE. There it suddenly becomes the only tray icon behaving that disruptive, since in KDE the normal behavior is: left-click brings up the "main window" and right click gives you a context menu of options (if I remember correctly this is also the old behavior on Gnome).
So like I said in my original (duplicate) report: it's fine with me if they want to fix all of it for Gnome, but they should keep it gnome-specific then to avoid this kind of disruptiveness on other DE's which they don't experiment on.
