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.
