I've written a review of Cairo, an application dock utility for Linux desktops, tested in Manjaro Illyria Xfce edition, including initial setup, detailed configuration covering appearance, animations, effects, themes, and add-ons, some problems, and more. Take a look. https://www.dedoimedo.com/computers/cairo-dock.html Cheers, Mrk
I used it a bit on Ubuntu a while back. I preferred the old 3D icon look myself. Eventually though I just went back to using the Ubuntu launcher.
With so many possible settings the ability to export the final configuration, including the chosen theme, is a godsend. You can then replicate the whole thing instantly on new installations with only a need to reconfigure items such as connection details for the system monitor.
