I have installed a crapload of new modules. First, let me mention sidecontent, which lets you create your own sidebar box. You should be able to see an example to your left. I replaced FCKeditor with quicktags, which provides some cute little fast-loading HTML editing buttons. It's not WYSIWYG, of course. FCKeditor will come back once I figure out how to add a "use FCKeditor?" option to the user's settings. Send provides the best "mail a node" functionality I've seen yet. Likewise, Print Friendly Pages does a very nice job of presenting a printable node view, complete with footnotes for hyperlinks. There are others, but these are the most visible.
