Cons
Con Poor/No system theme or icon integration
Docks use their own theme, own theme colors, icons, layout's and theme engines.
Con Hard/Underwhelming to configure
Cairo dock proposes a feature rich tool, tweakable to any degree. The configuration menus are at times inappropriate, shallow and uninteresting, complex to navigate, and prefab-centric. Rarely offering a satisfying preset, and always unsatisfying to tweak.
Con Can be heavy on resources for weaker systems
Cairo-Dock is more on the heavy side when compared to other docks, which is something to keep in mind for those that are on low resource systems.
Con Zero images
This is a pro for some but it's a con for others.
Con Compressed visual design
Much busier looking, less spacing or white space compared to similar apps.
Con Issues when Caps Lock is active
When typing with Caps Lock activated, it's impossible to use Backspace. Rofi eventually freezes in this scenario.
