I am sorry, I forget you mentioned you on v5. Actually, the request for it were put in by others couple of times before. But, I guess to implement it in a Fences area is not as easy as you think. Specially when Fences need it to keep track of all that layout within the Fences when user desktop changes resolutions and add or removed monitors etc.
Thank you,
