Problems using Anchor Point tool on 3D layers with the new Gizmos.
You used to be able to snap the anchor point to layers when using the Anchor Point tool (y) and pressing Shift or activating the snapping checkbox, now it doesn't work with the new gizmos.
Also... it's pretty useless defaulting to the same type of gizmo used for the SELECTION TOOL and not having any way to change it when you CAN'T rotate or scale an anchor point. Now you have to go to the select tool, select the POSITION gizmo and then come back to the Anchor Point tool again if you want to move an anchor point in XY space for example.

There are many problems with this gizmo, some workarounds are discovered along the way, but it remains one of the bad developments in the software. I don't understand why no positive developments have been made to it since its much maligned release.
