FictionalUI
1600X900wide
UPDATED for patch 4.3!

After playing WoW for 5+ years and being addicted to UI compilations, I finally broke down and made my own from scratch. This is simply many addons that I've used for years and all I did was tie them in together to make a nice clean layout mainly for a raiding healer setup. Don't fret though! If you are not a healer, this setup works fine on dps or tanks as well.

Setup:
1. Back up your WTF, Interface and Font folders and then delete them from WoW directory folder.
2. Unzip FictionalUI in your WoW directory.
3. Rename these folders in the WTF folder -
* ACCOUNT NAME replace with your account name (example: Katie86)
* SERVER NAME replace with the server you are playing (example: Mug'thol)
* Priest, Paladin, ect, choose your healer class and replace with the character name you play the most (example: Fiction)
FOR THIS COMPILATION TO WORK YOU MUST DO THIS STEP:
Log into your account, log onto your character, once in-game hit the enter button and type /reflux switch fictionalui - remember, it's case sensitive.
If any addon doesn't seem to load, type the appropriate /command for the addon and check for profile "fictionalui", "fiction" or the class type you are playing.
HEALERS: Technically your grid should be set up correctly per class if you followed my directions. But just to make sure, once your screen has reloaded after doing the last step above, type /grid, go to the Profiles tab and make sure your respective class is being used as the profile name. Example: Shamans, make sure your profile is set to "shaman", ect.

Non-Healers Notes: if you are not a healer and just like this compilation - choose the Priest folder, and rename it to your characters name. I have added in a profile in Grid just for you guys as well. Its smaller and uses less information. Go into the Grid profiles and choose "non-healer".

High-Res Notes:
You'll have to adjust the chat boxes by right clicking on them.
You'll also have to move the map or move the panels - I would suggest moving the panels by typing /kgpanels config, open the waterfall menu named Active Panels, and find the panels named Minimap, SLDT Map and SLDT Map 2.
You can unlock and move them by highlighting them in the waterfall menu and unchecking the "lock" option to the right.
Lastly you will move the Skada windows the same way using the slash command /skada config.
REMINDER: make sure you "lock" the panels again once you are done!

Bartender Notes:
There are two "hidden" bars to the bottom left and right of the screen above both chat boxes, all you need to do is mouse over them. Your Bags open by pressing "I". Your micro bar is directly above the right side chat box, and your Druid, Pally, Stance or Totem bars are directly above the main action bars. The XP bar is under the left chat panel, and the Rep bar is under thr right chat panel.
