When you are on the bar and the chances of getting back on are very slim (or non existent) it would be very useful to be able to leave autoroll on even when you leave the site, so that your opponent can carry on without you until a decision is required.
I realise that this is mainly an issue for those of us who play some matches without a timer and not face to face, but if it would be easy to implement it would be helpful.
Thanks
