Bit of a general question here. Is it possible in Ubuntu 18.04 to move things around on the top bar? For example, the date and time in the center -- can it be moved to the right to sit next to the network and power icons? Is this only possible on what I've read is called a "Unity" desktop? (sorry if it's a silly question, quite new to Ubuntu still).
Also, is it possible to use any icon one likes for things like the Trash bin on the desktop? For instance, I have an icon theme installed, but I don't like the Trash icon, could I use the icon from Gnome or Humanity for it instead if I wanted to?
