bartender for the action bars, squeenix for the square map, and possibly pitbull for the health bars.
Here is two shots of my UI, one in a raid, with only one other member my raid looks just like a 5-man cuz I dont need to see everyones health. The other is just me alone not in combat, also I added my bag UI as well.
My Add-ons, minus some simple ones like DBM and CTraid, gatherer etc.
Pearl - Health Bars, I like it cause it has a simple look, and has a combat bar that shows your health and mana wherever you want it, I have it at the bottom so I dont have to look up at my health all the time.
XRS - Shows the mana of all the healing classes and the health of the tanks, if you are raid leader or assistant you can have it check if all members have buffs.
eePanels - Simple movable/adjustable grey panels with a white trim, great for behind chat panels and buttons.
Bartender - Action bars, Simply the cleanest, easiest to use I have found. can resize and move up to 10 bars. note my trinkets.
Quartz - If there are any casters that aren't using quartz, they are really missing out. adjusts for latency (see the red part at the end) and will increase your dps by anywhere from 50 to 100.
Squeenix - Just makes the map square. ;D
SCT & SCTD - So much easier to see resists when they are right on the mob. left side shows when buffs/debuffs/heals are coming in, right side (not shown) shows buffs/debuffs leaving.
Prat - Just a chat program that simplifies what you read in combat log and regular chat.
ElkBuffBars - Simple way to see your buffs and how long they have left.
Ark Inventory - A great bag program that shows whats in your bag/bank, your other char's bags/banks, the guild bank. Also splits stuff up into consumables/quest items/ trade skill items/ weapons/armor/vendor trash etc. great program!
Dottimer - Great for a lock, tracks the dots you have on different mobs and how much time is left on them. Also works for things like rend, fecundity, etc.
Necrosis - Again a lock add-on, used to organize shards, create healthstones/soulstones etc. but I believe there is a similar add-on for most of the classes.
Almost all of them are ACE2 add-ons so i run the wow ace updater and it updates them all! yay!
