Please use XLoot now. Group is included.
XLoot Group - A replacement for the blizzard loot roll frames.
Requires XLoot
All options are available through /xloot group (Command line) or /xloot options -> XLoot Group (GUI). Each option is fully documented in the tooltip for it.
Group picks up styles from XLoot's appearance settings.
You can place Group anywhere you like by dragging either item rows, or the anchor.
You can show/hide the anchor at any time in Group's options.
Rows act like item links if possible- Shift clicking links them, Ctrl-clicking tries them on, and each has a tooltip for the item.
