I've just installed LXDE under Ubuntu 14.04 and I'm finding it much more agreeable.
One of the few problems is the fact that the network status widget/panel doesn't show up. I've read this is a known problem and that it can be fixed by manually adding the nw-applet to my default applications list.
The problem is that there is no Default Applications tab in my Preferences menu. Have I missed it or how can I add it back in if it really is missing for some reason?
