Hey, I'd like it if I could use Preferences to determine whether I even want the Virtual Machine Library to pop up. Personally, in my current configuration (and usage) I'd really like to just not even have it pop up at all. For me, having to already close it is kind of 'errrrggh'. And since most of my virtual machines are on an external drive, seeing a bunch of large question marks really doesn't help me much (when not plugged in to the external drive).
