Right now it's possible to restrict the machining area based on "bounding box", "silhouette", and a selected contour. I've often missed just being able to say something like "I want you to stay at x>25" because the part is clamped in the vise up to x=25. A majority of the time there isn't a convenient contour that mimics these constraints, but they are easily expressible as coordinate constraints. It would be great if you could restrict toolpaths based on XY coordinates just like you can in Z with the "heights" tab.
