In the latest build of Patch 10.0.7 PTR, there has been a few profession-related UI changes!
Profession Crafting Menu
It may be hard to see at first glance, but looking at the profession recipe menu on PTR vs. Live, you can see that the recipe menu for professions has been reduced in size.
Important Note: This only affects the Recipe tab of your profession menu. The Specialization and Crafting Orders menu remains the same size.
