I Have a Suggestion for Similar Worlds

Could we have a display at the side showing us friends that are currently online. And underneath that the notifications of what they're posting and commenting on. It's a pain changing pages or having to scroll down to the bottom to see. It would make it so much easier to follow our friends.
Also can you add to someones profile when the last time they were on was?
I know a lot of people have already asked if we can make our own groups but until you can sort this out please please please can we get whiteboards?? I don't want to have to pm people all the time especially when I end up having to repeat myself.
