Need better picture navigation

There are lots of pictures to choose from, but I wish it were easier to navigate the selection. The new ones are always at the end, so you have to scroll through all the others. It would be great to see completed and in progress pics with an icon on home screen. Also, having trouble with zoom in and zoom out because I often get the color I am currently using in places where I dont want.
