It's a small thing that bugs me. I want to know if people are away when I use /p on other servers. Currently you have to go to that server to see if somebody is AFK. Some may say it is a small thing, but it is a small thing that would make many people's playing experience a little bit better.
You're right, it's a small thing, but it's a thing I've noticed. I see no problem with adding this for all servers
