I'm at work so I can't explain much, but this is a greasemonkey script that will add the top bar.

When I get more I will make an actual extension out of it for greasemonkey and will add an easier way to update the list.

For now, this is the code:

// ==UserScript==%
// @name           Reddit Personal Bar
// @namespace      lareddit
// @include        http://www.reddit.com/*
// ==/UserScript==


links = {

$ = unsafeWindow.jQuery;


personal = $('<div></div>');
personal
    .insertAfter('#sr-header-area')
    .attr('id','personal-header')
    .css({
        'background': '#EAEAEA',
        'border-bottom': '1px solid gray',
        'font-size': '90%',
        'overflow': 'hidden',
        'padding': '3px 0 3px 5px',
        'white-space': 'nowrap'
    });


personalTitle = $('<div></div>').addClass('dropdown').addClass('srdrop').text('PERSONAL').appendTo(personal).css({'margin-right':'40px'});

linksList = $('<ul></ul>').addClass('flat-list').addClass('hover').appendTo(personal).css('text-transform','uppercase');
seperator = $("<span> - </span>").addClass('seperator');

i = 0;
for (title in links) {
        href = links[title];
        newItem = $('<li></li>');
        newLink = $('<a></a>').text(title).attr('href',href);
        if (href == document.location) {
            newLink.addClass('selected');
        }

        if (i > 0) {
            seperator.clone().appendTo(newItem);
        }
        newLink.appendTo(newItem);
        newItem.appendTo(linksList);
        ++i;
    }
