Multitabling on betfair - can it be made easier ?

why have they 9 or 10 seats even at 5 max tables , this messes up the hood , stats in wrong place etc.

is it possible to use the same 5 seats on every table . ie use say seat 1 , 2,3, ,4, 5 so that the your stats and hood are in a constant position.
wouldnt mind playing 8 ables of cash but find it imposssible on this site  due to issues with the hud

any suggestions on how to improve it. has anyone managed to play smoothly a lot of table with no problems with hem and hud etc
