What network manager to use for the Xfce4 Panel?

view story

http://askubuntu.com – I have installed Xubuntu desktop on top of initial Lubuntu 12.04 installation. How can I select between the wireless networks and how to see the app in the panel? I used Xfce in the past but I do not remember how to add it (I had it by default then I guess) I have installed Wicd and added it in a launcher , but I'm thinking about a "live" applet for the panel that I'm missing for the moment in Xfce.
