LootMagic was designed to save you the hassle of cleaning your inventory when you're looting and it is full.

Current Version built: 09/19/12 (WoW 5.0.5 just before Pandas)

Features:

FROM README PACKAGED WITH ADDON:

Replaces Autoloot.  Will work with Autoloot on or off, but the "inventory is full" goes away with it off.

Optimizes vendor trash sell values.  Stacked items are counted as a full stack for calculation, debating whether
to count as half stack.  Feedback welcome :)

Algorithm:
    Will dump lowest-valued trash for ANY common or greater quality item except what you define as (also) trash.
    Will dump lowest-valued trash for any trash to be looted that is higher in value than said item.
    Checks for item-specific bags, no mistakes therein.
    Autoloots when inventory not full and when inventory full.  and thus:
    Will make you win at life.
