I have installed Gnome Ubuntu 15.04 AMD64 on my Dell XPS 13. I would like to add an indicator next to the wifi and sound icons that shows network bandwidth usage.
It appears that netspeed fits the bill, but I cannot figure out how to add applets. I have tried holding Alt and right clicking in the area to the left of the icons, but nothing happens. I believe the correct term for the area I want to add this applet to is the Gnome panel, but please correct me if I am wrong.
