Does anyone know how to align applets on Gnome panel? For example I add notification area and there's five icons (you see it on the left of processor icon). Then, I plug my BlueTooth adapter out of my laptop and it's logo disappears, leaving blank space on the right side of applet.
Here's screenshot:

Same happens with any applet that's width can change (for example tray). Is there any way to tell applet "Move right as far as you can".
