How do I give the 2D cursor specific coordinates in 2.8? In the UV Editing Workspace in Blender 2.8, many of the features present in Blender 2.79's Image Editing Panel no longer seem present.

How do I type in specific coordinates I want the 2D cursor to be? How do I return the 2D cursor to the origin? How do I snap the 2D cursor to a specific vertex?
2D cursor to coordinates : you will find in the display drop down menu 



The Snap to options you will find in the UV Context menu (right click) :
