Allows you to combine your bags into a single, larger one, yet gives you the power to choose which bags to combine. Great if you like to combine your bags, but don't want to always see the contents of your soul shard bag or ammo bag. Complete with a user-friendly graphical menu for changing how your bags will display. Use /baudbag, or the menu button on any of BaudBag's containers, to change the settings for this addon.

With Baud Manifest, you can browse your inventory as a list, instead of the standard bag layout. Categories can be created to organize the list, allowing you to place items as well as other categories within them. Categories can be expanded to view the contents, or minimized to save visual space. The item list can be also sorted or filtered to help you find items. You can also view manifests of other characters, as well as a combined list of all your characters' manifests.

EngBags is an AIOI with autosorting fully configurable. It separate your items as you wish between 9 dynamic bars of items. The sorting is made using categories, which you can edit. These categories can do full text search on item tooltips, which mean you can make a category that will include all items wich tooltip contain "Increases damage and healing". With this you can assing that category into bar 3 and you will have all dps equip items in that bar. That's an example, but you can do what you want with this in means of sorting. EngBags come with predefined categories that will bring you sorting out of the box. It also sorts the empty bag slots for diferent bag types.
A replacement for the default game bags that combines all the bags into one frame. OneBag doesn't entirely rewrite the bag-handling interface like others do. It simply rearranges the bags into one and allows the default UI to continue managing the bag slots. This means that addons such as KC_Items, ItemSync, LootLink, and SellValue should be inherently supported. As long as an addon is compatible with the default game bags, it should work with OneBag.
This is in the early stages of development and is not complete. It may not be yet suitable for full-time usage. Since the last major development work was done on OneBag3 I've had a lot of ideas about what could be done to do it better, and being perfectly honest, I had gotten to the point where I had coded my way into a corner on OB3. Some of the ideas worked well. Some did not. So I'm going to take another stab at this, if for no other reason than to get the ideas out of my head!
Provides an alternative bag and bank interface. Features include searching for items (in mail, etc.) You can also see and use the original default UI bags, which have slots free overlaid on top of them. There are also many convenience features, like highlighting new items, colored spotlighting, and purchase bank bags without having to unload the addon. A visual edit mode allows you to rearrange categories to your taste, and an advanced customization window enables you to completely configure every aspect of TBag.
AddOn that you can use to filter the guild bank. No more searching for that single item you know is there. Just type the first few letters of the items name and watch as it appears before you.
BankStack sorts your inventory, bank, or guild bank; fills incomplete stacks in your bank with items from your inventory; compresses your bags by filling incomplete stacks within them.
Full bag, bank and guildbank sorting addon with the following features: Changable sorting order, Ignorable items, Automatic action (here's where the genie comes in), Item stacking, Item moving (move special items to their special bags).
Usage: /genie work
All your bags and your bank bags have a checkbox. If the bag is checked then it will be sorted. If it is unchecked then it won't. To sort your bags, there is a button on your backpack. To sort your bank and bank bags there is a button on your bank tab. To sort your guild bank there is a button on each tab.
BagSaver will help you keep your bags as clean as possible. Helps overcome your bags being full as your levelling/doing dailies/instancing. The goal of the addon will be to keep your bag slots clear of things you don't want, and assist you when your bag does somehow become full in finding the optimal (read: least valuable) item(s) to discard to make room for something better.
This mod tracks the items of your characters and displays the information when you hover an item in your bags. It will record items that are equipped, bank, bags and items in your keyring.
This addon keeps track of all your items in your bank / bags / equiped and all your tradeskill items in your tradeskill windows for all your characters (per realm & per account). The items ( bank / bag / equiped ) get updated only when you open your Bank. Tradeskills get updated everytime you open a tradeskill window (this includes Cooking etcetera). To view the list, goto social (O), then click the "Bank" tab at the bottomright of the social window. In this BankList window you can click a single item to get detailed information, or filter the list by selecting a character from the dropdown list, or type a searchtext to show only those items. You'r characters will get added to the dropdown list once you have logged onto them.
Remembers the contents of your bank, bags, mail, equipped, currency, keyring and items on AH and display them anywhere in the world. Also able to remember/display the banks of any character on the same account on any server, as well as searching and exporting lists of bag/bank items out.
Exonumist adds information to the tooltips in the currency window showing how many of each token your other characters have. There are no options; it just works. Obviously, you must have logged into a character at least once since installing Exonumist before information about that character's tokens will appear in tooltips.
MobileVault allows you to take a snapshot of your guild bank and view it from anywhere. The addon also provides item counts on the tooltips, from any vault you have scanned.
oGlow will light up your items, by adding a quality border to them. It will only display this border for common quality items and above.
With Patch 4.1.0 all bags are opened on accessing the Bank / Mailbox / Vendor with the default UI.
This "AddOn" changes it back to previous functionality, so that only the backpack will be opened.
UberInventory keeps track of where you have your items stored as well as how much cash you own, it even tracks the amount of cash attached to mails that you haven't collected yet (this is only done when visiting a mailbox).The information that has been collected can be viewed anywhere within the game, so you never need to be at the bank or guildbank to be able to see what is stored there. What is even better if one or more guild members have UberInventory installed as well, you will receive the latest information of what is stored in the guildbank (and guild cash) after they have visited the guildbank.
