There's been a few times when I am at my forum's main page and at the bottom it has people who are also on my forum (Currently Active Users). This is displayed as:

1 (2 members & 1 guests) Moderators : 1
KingBean, Joe Blow

It interests me to know what threads the other people are reading. I know I can get to this through Who's Online, but would it be possible to have it so that I can mouse-over the username to see what they are doing?

i.e. if I mouse-over my own name it would have "Viewing Forum:
theBeanScene online freakin' forum" or "Viewing Thread: Test Post" etc.

In User Profiles it has "Current Activity" info, so could this be copied to the usernames...?
