2 things. users online display/public profile

If i should have made these two questions in two seperate posts, i apologize in advance.

1. I have the useronline plugin from lesterchan. it works rather nicely but i would rather it display who is online rather than how many people are online. (i.e rather than ‘3 users online’ have it say ‘billy, johnsmith55, janesmith,’)

2 i would like a way to make my user’s profiles public by simply clicking on their user name (when it is displayed next to a comment or ((if question number 1 is possible)) displayed in my menu/sidebar under users online)
