*Player

The core of Quartz is lightweight implementation of a standard casting bar, with configurable size, text and icon positioning, and colors.

*Target/Focus

Implementation of target and focus casting bars in similar fashion to the player cast bar.

*Buffs

Display of target and focus buffs and debuffs as duration bars using the new API introduced in patch 2.1.

*Flight

Hooks into FlightMap or InFlight to display the current flight progress on your casting bar.

*Global Cooldown

Displays a tiny spark-bar to show your Global Cooldown near the cast bar. Helpful for those who'd rather not squint at their action bars to see when they can cast again.

*Interrupt

Changes the color and text of your casting bar to help show that your cast has been interrupted (and show who interrupted it).

*Latency

Displays the amount of time spent between cast send and start events, in the form of a bar at the end of your casting bar, with optional text that displays the actual duration of the lag. This helps in canceling casts when they will not actually be interrupted, especially for users with consistently high pings.

*Mirror

Shows the 'basic' timers such as breath and feign death, as well as some 'odd' ones such as party invite time, resurrect timeout, and arena game start, and a framework for injecting custom timers into the bars.

*Range

Recolors the casting bar when your cast target moves out of range mid-cast.

*Swing

Displays a swing timer for your melee weapon as well as hunter autoshot.

*Timer

Allows for creating custom timers displayed on the mirror bars.

*Tradeskill Merge

Merges multiple casts of the same tradeskill item into one big cast bar.

Installation Guide
Exit "World of Warcraft" completely
Download the mod you want to install
Make a folder on your desktop called "My Mods"
Save the .zip/.rar files to this folder.
If, when you try to download the file, it automatically "opens" it... you need to RIGHT click on the link and "save as..." or "Save Target As".
Extract the file - commonly known as 'unzipping'
Do this ONE FILE AT A TIME!
Windows
Windows XP a built in ZIP extractor. Double click on the file to open it, inside should be the file or folders needed. Copy these outside to the "My Mods" folder.
WinRAR: Right click the file, select "Extract Here"
WinZip: You MUST make sure the option to "Use Folder Names" is CHECKED or it will just extract the files and not make the proper folders how the Authors designed
Mac Users
StuffitExpander: Double click the archive to extract it to a folder in the current directory.
Verify your WoW Installation Path
That is where you are running WoW from and THAT is where you need to install your mods.
Move to the Addon folder
Open your World of Warcraft folder. (default is C:\Program Files\World of Warcraft\)
Go into the "Interface" folder.
Go into the "AddOns" folder.
In a new window, open the "My Mods" folder.
The "My Mods" folder should have the "Addonname" folder in it.
Move the "Addonname" folder into the "AddOns" folder
Start World of Warcraft
Make sure AddOns are installed
Log in
At the Character Select screen, look in lower left corner for the "addons" button.
If button is there: make sure all the mods you installed are listed and make sure "load out of date addons" is checked.
If the button is NOT there: means you did not install the addons properly. Look at the above screenshots. Try repeating the steps or getting someone who knows more about computers than you do to help.
Translations
When you download a mod, please be sure that the mod is compatible with your translation of wow. Some mods only work on the US versions, while some only work on some of the various European versions. These variations are called "Localizations".

TOC Numbers (Out of Date Mods)
When Blizzard patches WoW, they change the Interface number. This means that all mods will be "out of date" unless or until the author releases a new version for that interface. Some people go into the .toc files and update the numbers themselves, but this is STRONGLY advised against as it will cause problems locating possible incompatibilities addons. When you log into WoW after a patch, you DO NOT have to delete your interface directory. All you have to do is simply tell WoW to ignore the interface numbers and load all the mods anyway. All you have to do is, while at the "character select" screen, look in the lower left corner and click on the "addons" button. A window will pop up listing all your installed mods.

If you look in the upper left corner of that window there should be a box that says "Load Out of Date AddOns". You want to CHECK this box. Now simply go into WoW normally and all your mods should load. As of the 1.9 patch, you will have to do this after EVERY patch/update that Blizzard posts! If you encounter any problems with a mod after a patch, please be sure to let the author of the mod know so they can fix it.
