Here’s a brief overview of what add ons we have in there, and what they do:
AdvancedFilters
Adds a bar with sub filters to your inventory and bank, makes finding things easier.
AIResearchGrid
A window that allows you to browse through your characters’ researched traits, very nifty for showing you what has and has not been researched yet

AwesomeGuildStore
Makes guild stores function the way they always should have. Remembers search selections, adds a nifty category menu, and allows filtering above the displayed results.
Binder
Allows you to save key binds via /binder save your_name and load them again with /binder load your_name. Very neat for having a special set of RP key binds where you don’t accidentally jump all the time.
BugEater Zbug
Makes error popups go away and displays the output neatly in your chat.
CDGBankStack
If you have something in your bank, upon opening the bank all the items in your bags get stuffed in there if the stack in the bank isn’t full. Eventually I’ll fix that functionality in Stacked again, but for now that’s that.
CraftingMaterialLevelDisplay
Add the information what level the materials are for to the tooltip of crafting materials.
CraftingStations
Displays items for all crafting stations on the map, together with what they do.
CraftingSwit
Displays a little list with the things you have to produce for the CraftingWrits.
Destinations
Handy for completionists and achievement hunters, this add-on displays map markers for everything and its dog. If you’re new to the game and want to explore everything on your own, you should disable this.
Dustman
A junk manager. Default configuration is that grey items without any further value get junked. Whenever you talk to a vendor, all the junk in your bags gets sold automatically and the notification is skipped.
DyeLinks
Lets you go directly to an achievement from the dye station
FCOStarveStop
An add-on that reminds you to renew your buff-food
GuildStoreSearchEx
Allows you to scan guild stores and adds information to the item tooltips how expensive something was.
HarvensAliases
You can create aliases for things, such as /rl and /reloadui or such.
HarvensBagSpace
Displays your bag space in the loot window
HarvensChatCompletion
Offers auto complete when you type slash commands into the chat
HarvensCustomMapPin
Allows you to add custom map pins via button push. Pins can be shared via chat. Incredibly nifty for marking RP locations!
HarvensStackSplitSlider
A Elder Scrolls: Offline - style slider for splitting stacks
InventoryInsightFromAshes
The addon that has caused me to start developing - keeps an account-wide database of everything in the pockets of your characters and your bank, accessible from everywhere.

ItemSaver
Allows you to save items, which will then not be displayed in situations you chose (research, vendor, deconstruction)
KeybindSearch
Lets you search through your key bindings! So nifty...
LootDrop
For those who play with auto loot enabled: A draggable list of what you loot
LoreBooks
Similar to SkyShards this add-on displays the location of lore books on your map
LostTreasure
Adds little X-es on the map when you have a corresponding treasure map or crafting survey
MailBuddy
You can create a list of recipients and subjects, which you can then add to the corresponding fields in your mailbox via a simple click.
MailerDemon
Allows you to add preconfigured buttons to your mailbox that send stuff away on click - you can set what should go to whom.
MasterRecipeList
A list of all recipes, nifty for keeping track of them
MasterThief
Makes the life of a thief easier
MerAchievementFilters
Finally brings some sort of order into your achievements - you can, for example, search by dyes.
NoThankYou
Allows you to disable a lot of unwanted things, such as raid score notifications and, most important for roleplayers, the bag/map animations upon browsing a menu. Make sure to have the last two points checked.
NPCMuter
"Hey, FancyMan! Fallen on any swords lately?" - NO MORE!!!
pChat
Allows further chat customisation, including aliases for guilds and better colours
Recharge
Recharges and repairs your gear for you, you can set the threshold yourself
ResearchBuddy2
Makes little icons next to researchable things, telling you whether or not you have already learned this trait
RollingStones
Auto-banks your Tel Var-stones for you. Used to be a big deal when IC came out, but still nice to have.
SkyShards
Displays Skyshards on the map
SimpleGroupLeave
Allows you to leave a group by typing /gl in chat
SimpleHelmetToggle
Allows you to toggle your helmet via /helmet or key bind
SocialIndicators
Shows you in chat and when facing someone if they are on your FL or in your guild
SousChef
Allows you to mark recipes and keeps track of which recipes you don’t have yet
SwitchBar
More mana-created add-ons for you - this one displays one of two icons, depending on which skill bar you're currently using.
SyncMotes
The emote addon for roleplayers: It allows you to trigger emotes when you say certain phrases. I suggest you look up how exactly it works, since it’s rather complex.
UltimateUIHider
An alternate “hideUI” keybinding, one that actually hides the UI. Makes sure you don’t have these horrible party markers on your screenshots.
UnstuffMyBags
Throws away / junks style materials on keypress and allows you to bind keys to junk / destroy item
Zolan's AutoRepair

Wykkydd:

Outfitter

Toolbar
A toolbar that displays a bunch of additional information, such as bag space, number of soul gems, research…
