One consistent problem I'm experiencing is that I loose spatial ability to manoeuvre an object's boundary box. Insofar that the frame is white all round.
It would be very useful if one side of the box had a coloured wire frame so that one can associate that face to the direction of the object within.
Because at the moment I can't tell which way the object is facing, especially if I inadvertently flip the image when altering say the object's rotation.
