I have one issue with the new feature (newly shared photos).... I was at a friend's the other day, and pulled up ATP as an example to her of a website design style she might like to use for her business. she was VERY impressed with the sidebar menu, until I scrolled down and it disappeared.
One of the things I love most about the sidebar menu is that it follows you as you scroll down the page. With the recent photos, the sidebar no longer follows me when I scroll down the home page.
