new feature suggestion

hey, i don't know whether everyone agree with me or not but i personally think there should be a ‘hidden’status where people would see you as offline when you are online. sometimes it gets very awkward when you are playing with one of your friends and the next thing my other friends want to join in but the friend i am playing with refuses to play because my other friends are 'not very good'. this makes things so difficult as i have to make decisions about who should i play with and how to comfort the others as to why i can't play with them. it would make life so much easier if there is a 'hidden' status so that i can play with individuals without upsetting others. oh and i don't really know whether this should be posted here? if im wrong please correct me.
