I just got done browsing through tfabris' excellent "What's cool..." thread here and as a brand-new Mk2 owner (queue number 720, but had to defer for financial reasons...) thought that a great "companion" thread would be about what sorts of tips'n'tricks those of you lucky enough to have had yours for a while have come up with? Things that aren't so obvious in the UI, a nice way of ordering playlists for easier retrieval, interesting software hacks, unusual installations or usage (a friend of mine insisted once that he was going to put his empeg in his airplane when he finally got it, but has since had to sell the plane) that sort of thing.
