I recently installed the Window List Group applet to free up some window list space. The applet groups you normal icon+text entries to single boxed icons that have the potential to expand beneath them, much like Windows 7. When I added this applet, it was centred at the top of my screen, which I did not want at all. To remedy this, you must dive into the dconf editor for a quick change.
If you haven’t got it installed its
sudo apt-get install dconf-tools
Then, navigate to org >> cinnamon. Now click on the item “enable-applets”
You will want to look for your “centered” panel in the list of “enabled-applets.” Once you change this to “left” and restart cinnamon, you should be good to go.
