Anyone know how to get more screen saver options, like choosing how many seconds to show each photo, or choosing different effects.. in my options I can either crossfade or not, or zoom/pan or not. Also the "shuffle" options is not so great, to this day I don't understand why no apple product has proper shuffle. If I have a folder with 500 photos, none should repeat until all have been displayed.. Anyone know of a third party screen saver app that can do what I'm looking for? Thanks!
