Why is the ref so far away?
In tennis or badminton, the ref is very close to the action. Even in traditional courts the ref sits near. Then why during matches played on glass courts the refs sit so far away. Making decisions on doubles, lets, in/outs from so far away must be exhausting and prone to errors (either making wrong decision or not seeing error). Just roll up a high chair like in badminton or tennis and prop it up on the left or right wall so they don't obstruct the camera and call it a day (make it extra spicy by propping the chair behind the front wall). All this talk about making changes rules and policy, asking for good behavior on court, etc etc, this is a cheap tangible solution that can be implemented and tried and if doesn't work change it back.
