Since the data is there but is hidden by Crafting, I suggest that a small window is added (like Gathering) that includes all unlearned recipes from that list.

I think allowing you to view unlearned recipes in TSM would be awesome! Especially if I could then add them my queue and task list. This way when switching over to my AH toon, I'll have a shopping list of things I want to look for when the prices are low. Just my two copper.
You can use the "default" button to easily toggle between the default ui and TSM to see your unlearned recipes. No need to disable crafting

The stock Crafting GUI has an "Unlearned" tab that shows all missing crafting recipes that you need. It also list how to get them. I am constantly having to disable TSM_Crafting so I can look at this resource quickly and easily in game without having to resort to an out of game resource.
That would be useful, so I could see what should I learn next, what recepies has the best profit without looking up the final product in AH.
But maybe not so useful in Legion, would've been better in WoD.
