NateManaged to get just a little bit ahead in my classes, so I did a small bit of work on #Sunstone today after work. The feature I just added is bookmarks in the sidebar. Works decently well so far, but I'll eventually be adding a setting to choose whether it opens bookmark links in the current tab or in a new tab (right now it defaults to a new tab). There is a history tab in the sidebar which still isn't populated, but that will happen soon enough.
