Nice update in general. Good idea to add that mobile preview option. I personally don't really care about mobile layouts, but it's good that those that do care can optimize the designs for mobiles while still on pc. Just 2 negative remarks: The major one being I can't upload files using the sidebar on the right, but I read it has been reported already. The minor one being that the edit summaries for undoes no longer says the "undo revision xxxxxx by ...... (talk)", without having to copy/paste it from the text under the summary box. (both issues were noticed on fallout.wikia.com).
