Plugin Update

I have a "Friend's List" Wordpress plugin I need modified. Here's what I want to modify... 1.) Instead of just username, I would like to display user gravatar instead. 2.) I would like to be able to limit the number of friends shown in the sidebar. 3.) I would like the ability to set the size of the gravatar shown in the sidebar. 4.) Display a link to see "More Friends" this would take them to the author's profile where a block would display gravatars of all friends. 5.) I need the ability to modify how many friends are shown in the profile page at a time. Any number after would be displayed on other pages or tabs. 6.) Seperate the "Add Friend" button into it's own code so I can display other places than the sidebar. 7.) Change the "Add Friend" button to a link rather than button. Also simply display "Add Friend" or "Remove Friend". 8.) When a person adds another author as a friend, they are added to that person's friend list.
