The Plank is nice, but I would prefer to have launch buttons for my installed software applications (like Firefox, Libre and GIMP) located instead within the (top) pane/doc.
As is shown here. http://www.ostechnix.com/wp-content/uploads/2016/04/Budgie-desktop-file-manager-2.png
How can I do this? I am using Ubuntu Budgie 18.04 and the “add applets to panel” function under Desktop Settings only lists Budgie apps not installed software.
