Currently viewing on an iphone. Example: Rice-52.
1. "Background" images show up as a strip down right side revealing only a hint of the image. Personally I have never liked the implementation of background images. I rarely saw one that didn't make the page look busy or cluttered. So I don't mind its removal. But this isn't a removal. It's now a vertical strip. If that's how it's going to remain then most pages with background images should probably be redesigned to either remove or change the background image to something appropriate for a vertical border.
2. personal memories show up on some pages and not others. On my profile it only shows up in private view which I suppose makes sense. In Rice-52 it shows up on neither public nor private profile. Frankly this is another feature I've never been fond of. It makes no sense on older profiles and is often used incorrectly -- people placing content there that should be incorporated into the narrative.
3. Ditto with what used to be the secondary set of tabs (tree, descendants, etc). On those pages where it does show up, it's piled at the top of the right hand column further pushing down comments WAY "below the fold" which has always bothered me. Comments should be far more visible than they were and now are even less visible. On other views, the secondary set of tabs doesn't show up at all. Haven't yet figured out what if any pattern is being followed.
4. On iphone, font is fine. As I recall from laptop, I concur with others, the font is too light/thin and is difficult to read. I'll post more later from a laptop view.
