For more advanced document editing it would be very convenient with a feature identical or similar to Microsoft Word's style guides. In my opinion, it is one major feature missing from Word which inhibits editing. That is, colors in the left margin that signify what style that is in use for the corresponding paragraphs. Googling for "Word style guides" gives this screenshot as example: http://www.google.no/imgres?um=1&hl=no&sa=N&biw=1105&bih=694&tbm=isch&tbnid=EpU4oid0vXexNM:&imgrefurl=http://www.pcmag.com/slideshow_viewer/0,3253,l%25253D254967%252526a%25253D254965%252526po%25253D1,00.asp%3Fp%3Dn&docid=UlkEDlLmYWlk2M&imgurl=http://www6.pcmag.com/media/images/235534-microsoft-office-for-mac-2011-style-guides.jpg&w=630&h=440&ei=tcHGT-6UBYrf4QTXwoCZCw&zoom=1&iact=hc&vpx=344&vpy=136&dur=295&hovh=147&hovw=211&tx=140&ty=76&sig=108928579577025481388&page=1&tbnh=147&tbnw=211&start=0&ndsp=16&ved=1t:429,r:1,s:0,i:71
