Pro Panel mode
For those that do not like the OSX dock look there is also a panel mode included that pushed the apps to the left side of the panel and elongates the dock to fill the entire bottom of the screen, just as a regular OS panel would.
Pro Plugin Docklets
Docky provides simple applications that run inside of the dock such as a clock, weather forecaster and CPU monitor. These provide an easy way to see information without having to open up separate apps.

Pro Case insensitive

Pro Clipboard history extension

Con Removing Docky icon is not as easy as it should be
gconf editor is required in order to remove the Docky icon from the dock, which seems unnecessary as the setting exists, it should be in the app settings instead of hidden away in gconf.
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.
