There's not a way to do visible edit handles in CC3, but using Show Frames (Ctrl+F) will show the lines connecting the individual nodes as if the curve were the uninterpolated polygon. Being able to see where the frame bends makes it easier to hit the nodes to move things. It's certainly not easy by any stretch of the imagination, but it's much easier than trying to guess where the handles might be.

Putting in edit handles for path nodes is on my list of things to do, but I don't have anything resembling a schedule for when that feature might get implemented or released.
