I would like something simpler, Instead of having menu's buried in more menu's and the need to place shortcuts all over the hot bar.

How about the ability to click on the materials needed to craft the desired item, which would -Highlight- and when we click synthesize, It will craft the highlighted Item.

Once the item has been created, The crafting screen will return you to the previous screen, (Which would be the desired item), From there you continue to craft the required items from the one screen without needing to swap all the time.

For Items that Cannot be crafted by your disciple of hand, A simple popup tooltip stating the disciple needed will do, else a small "Unavailable Symbol"

But yes something needs to be done about this because it's to much work just for something so simple. Things like this convenience is key!
