GatherSage shows you if you can collect tradeskill items based on your current skill in that profession. It displays this information in the tooltip when you mouse over a tracked item on the minimap (Herb or Ore node) or the item in the worldframe (Herb, Ore Node, Skinnable corpse) or in your inventory (Millable herb or Prospectable ore).

This is the original GatherSage updated in both content and code for WotLK.  All new collection tradeskill items have been added: now supports Mining, Herbalism, Skinning, Milling (Inscription), and Prospecting (Jewelcrafting).

Will only show necessary skill levels if you posses the matching profession.  Also code optimized so that Herbalism info only shows on the Herb nodes instead of the picked herbs as well (due to the fact that the nodes and the herbs have the same name)
