I’m configuring Ubuntu MATE for a friend and he only wants one panel. He of course needs a wifi indicator in the panel but the only way to do that seems to be by adding the whole notification area applet which takes up a ton of space and has lots of indicators he’d never use. I’m really surprised something in Linux has no customization at all. I don’t see a way to remove any icons or reduce the space between them.
Of course, being able to add those indicators separate of the whole panel would be better.
