I'd love to see the Parallels icon in the Mac OS X doc be descriptive enough (either with custom text per icon or custom icon per guest OS) so I could tell at a glance at least which guest OS was running, if not the name of the Parallels VM. Thanks for a rocking beta Mac OS X product. After only one day, I'm stoked!
Yeah, at a minimum, the information used when configuring the VM (guest OS class and specific type) could be used to customize the icons with the OS name or logo or something like that. I'd also like to see the Dock menu for the application have some basic options added to it, such as "Suspend", "Pause", and maybe even "Capture CD/DVD" and "Eject CD/DVD". That'd be handy.
