Simply put, while it may clutter options, it would be a nice QoL, but [not a mandatory one.]

if you can Rclick any item and see if they have a crafting process for it, seeing as if you search most crafted items by What They Can Be Used with to Crafter other items.(Mostly Clothing) but not what the specific recipe to make the item you are Rclicking on.

It would make it easier for intermediary items to find its crafting spec outside of specifically looking in the search tab of the Crafting window. and make an easier search for it that going over the entire lists.

we currently have:
Search (what craft the rclicked item can be used it)
Search (item location/s and quantity)
Search Gathering Source.

but no reversed progression of search, as in searching the recipe for the item you obtained/crafted.<usefully for any crafters or players that general check the MB or players that want to craft a HQ version of a item. and more easily progress through what items then need to buy/gather from the mb, if they don't outright buy the finished product. or in specific circumstances. said item is untradeable after crafting.>

Don't expect much in replies, but throwing it out there.

As is its a extremely minor, but likely appreciated if it ever does gain implementation. <and no future upgrades to the current crafting menu/search is made>
