Learnable by.... addon
 

I used to have an addone that would add a line to the tooltip of a recipe if one of my alts was able to learn the recipe or would be able to learn it soon.

plus im also looking for another that added a line to say what recipe a certain reagent was used for by holding shift it gave a large list on the tooltip.

I think Altoholic does the "Learnable by ..." tool tip line. The other one might be Mendeleev.

once again a member of the community hits the nail on the head first try!!!!! thanks!

TradeSkillInfo does this as well.

One of the things i like about TSI is that it includes a searchable list of all tradeskill skills, searchable by both name and by reagents.

Does Tradeskill info replace Mendeleev?

Edit: Hmm. No update for 4.0.1 - but found a version at wowace - http://www.wowace.com/addons/tradeskill-info/
