Here's something that I - the noob - have always wished for (with official FW, and now with WDlxTV):
It would be nice, and useful, if we could have the screen saver changed to the thumbnail of the MUSIC media playing.
Let's say you are playing a random-shuffled playlist of your music media that's going to run for hours, when the box is going to display-sleep (screen saver kicks in), you would see the album cover of the active song as screen saver bouncing around instead of a fixed image!
I'm not sure if it could be accomplished or even if more people would like this but I certainly see a use for it.
Maybe we could vote for this by replying to my post here and showing interest in the feature and for the developers - b-rad et-all - to tell us if it is possible or not.
