Lets grap a face and press g and one of the axis. That still works but in 2.79 you could press the axis again and now locked it along the normals.
Is that gone or a bug because pressing one of the axis two times will do nothing and its still locked to global axis. Only when you press it the third time its unlocked.
Its just strange to me or i missed it that such a useful feature is not there anymore?
The blender manual is describing it but for me its not working.
