A quick note here: Don't go too crazy right away if you are new to WoW addons. Some mods can be very overwhelming and frustrating if you aren't familiar with them. Installing Pitbull could leave you overwhelmed with the customization and underwhelmed with the results. Also, expect them to not be just plug and play, but rather to set aside time for making your UI. To give you an idea, on some of my more elaborate UIs I could find myself dedicating an entire night to just fiddling with things. Don't let that scare you from experimenting.
