About

XLoot is a group of addons which improve looting in WoW by replacing default frames.

XLoot Frame: Replaces the Loot Frame, adding more information and behavior/appearance options.; Adds rule-based auto-looting options; Allows you to link entire loot drops in chat
XLoot Monitor: Shows a "toaster" for looting items, similar to Guild Wars 2, allowing you to either more visibly see what you and others loot, or remove loot messages from your chat box all together.
XLoot Master: Provides a more convenient Master Looter menu
XLoot Group (Please read in-game warning): Replaces Group Loot frames, modifies Loot Alerts/Bonus Roll frame; Group frames display current roll choices, the rolled numbers, and the winner.; If you experience any problems rolling on items, please disable XLoot Group and post a report with any error. While this is extremely unlikely, it is not impossible.; I understand this may cause you to lose out on a item, which is extremely unfortunate.; The rest of XLoot can be used safely without Group.; There is a Blizzard issue when you are the opener of a chest in Group Loot mode, your rolls will not be visible to your client nor will the events XLoot use fire. From my experience, your roll is still counted on the item, however. See this bug report: http://us.battle.net/wow/en/forum/topic/15508091093

Any of these modules (Frame, Group, Monitor, Master) can be disabled like any other addon if you do not want their functionality.
