For the Screensaver, it seems you can only choose a folder from a USB drive. It would be nice to beable to select a specific folder from a network share so that it doesn;t include the music and videos cover arts.
Same for the Photos categories, it would be great to be able to default to one specific folder instead og having to select media library or Folders and then have to browse to the Photos folder.
The basic slideshow and the screensaver is well... basic. While it serves it's purpose I'd really like to see something with a bit of design to it.
For instance, I really like the Windows Media Center style. If you're not familiar, it displays a "table" of photos all in black and white, then it randomly moves about and slowly zooms in on a photo, bringing it into color. Following that there is usually a few nice slower and smooth transitions to more full-size photos, sometimes those are even from the same photo set (located in the same folder). Then eventually it zooms back out to the "table" and begins the process again.
Now I know we may not get this exact thing, but some other "styles" of slideshow would be nice. Just something slicker and less basic.
