FarmIt allows players to actively monitor how much they have of any item. This is especially helpful when farming for items that cannot be placed on an action bar.
For example: use FarmIt while farming elementals, so you know how many motes you have without having to dig through your bags and count them.

Glyph Reporter manages what Glyphs are needed on a realm-by-realm basis. When a Glyph is hovered over , the tooltip reports any known characters needing that glyph. It makes inscription disbursement quick and easy.
Adds SpellIDs and ItemIDs to the various ingame tooltips.
iTip enhances item tooltips with useful information the game fails to display. I wrote iTip because I found other item tooltip addons to be a bit bloated for such a simple task. This addon is extremely lightweight, and self-contained.
Adds all sorts of information to an item tooltip. Including but not limited to: Where items drop, who drops the item, droprates, how much rep you need for an item, what food type an item is, what professions can make an item, what professions can use this item, what profession can find this item, which items you can make that you can use this item in, what mining nodes certain gems come from and item stacksize.
Changes the "Reforged" line in tooltips of reforged items to a more meaningful line showing which stat was reforged. For example the "Reforged" line in a tooltip would turn into "Reforged (Spirit -> Haste)".
Shows the Average iLevel (AiL) of people you target in the tool tip. There is also a simple caching mechanism in order to not repeatedly inspect people that you already have data for however you can force a inspect of your target by typing /sil target
The GoingPrice_Wowhead addon uses the LibExtraTip library to display various price statistics from Wowhead.
