I tried a simple search and didn't see it, but It would be cool to have more than just a generic Apple or Windows icon in the VM listing. For MacOS, it would be cool to have the official logo for the specific version (Lion, etc). For Windows, something that would be nice looking at a glance and/or perhaps include the version number overlaying the image. Even better would be the ability to use custom icons for each one as some of us have things like multiple versions of Win10 listed. For now, I simply integrate the version numbering into the VM's name and description, but this would make it faster to find what I want to click on in a list of 2+ dozen.
