XLoot completely replaces the blizzard loot frame. XLoot is draggable, scaleable, colorable, and configurable.
Options

All options menus are available through various methods, in addition to /xloot (command line) or /xloot options (GUI).
You can right click on the border of the loot frame for quick access to the options menu, or on any anchor for it’s menu.
Master Looter’s priority menu is accessible through “Options Menu” in the dropdown itself. All menu items have detailed tooltips explaining what each option is.
The border/background colors for all the frames can be changed, in addition to the default of letting them pick up the quality color of whatever loot they contain. (See Monitor in the screenshot) All color related settings are in /xloot appearance, or the Appearance heading in /xloot options.
