I learned yesterday how to add a second taskbar for cinnamon on my second monitor.
When switching to cinnamon, I was a bit bothered by the bottom taskbar not duplicating itself on both monitors
primary monitor
configuration
secondary monitor
I learned a bit more how to mess with the applets and panel settings. Also the panel that you are actively editing will be highlighted red
if Cinnamon had shipped with Numix-Square-light, I probably would have not been as exploratory.
