This little script improves the usability of friendfeed's navigation. Fixing the sidebar menu is a great idea that eventually let users to check personal lists and rooms without any interruption. Quick access links for personal comments/likes are what I exactly need. It takes you directly to the commented threads with a single click. The ordinary flow was requiring 3 clicks which is a significant time-loss.

As a final notice, I had to exclude (comment-out) the following line because the script did not work properly with greasekit.

$ = unsafeWindow.jQuery; 

I also added a link for the user's discussion page:

                //styles
                var likesStyle = 'style="padding:4px 0 2px 18px; background:url(http://friendfeed.com/static/images/smile.png?v=2) no-repeat; font-size:10px"';
                var commentsStyle = 'style="padding:4px 0 2px 18px; background:url(http://friendfeed.com/static/images/comment-friend.png?v=2) no-repeat 0 4px; font-size:10px"';
                
                //paths
                var me = $('.me .mainlink a');
                var sidebar = $('#sidebar .container');
                
                //hrefs
                var likesPath = me.attr('href') + '/likes';
                var commentsPath = me.attr('href') + '/comments';
                var bothPath = me.attr('href') + '/discussion';
                
                //some DOM manipulation
                me.after('<br /><a href="' + bothPath + '"' + commentsStyle +'" class="commentsNlikes">Both</a>');
                me.after('<br /><a href="' + likesPath + '"' + likesStyle +'" class="commentsNlikes">Likes</a>');
                me.after('<br /><a href="' + commentsPath + '"' + commentsStyle +'" class="commentsNlikes">Comments</a>');
                sidebar.css('position','fixed');
                
                //override FF's default link click method
                $('.commentsNlikes').bind("click", function(){
                	$(this).removeAttr('target');
                });
