as far as I know this is not possible to do from outside WMC. WMC is a screen hog and likes to be in front of everything else. It might be possible to do something from inside WMC. Possibly there is a command to show a picture, and you could create a picture of your commands, but this would not really be an overlay because it would probably take you to the photo section... Hmmm, I wish WMC was not so greedy because it ruins the command OSD popup windows Vox creates. Probably a WMC plugin could do it. You could suggest such a feature to the developers of VMC Controller. So far they have not responded to any of my posts though.
