I'm planning on making a Vista themed menu for the new PortableApps Menu. It will have glass and I hope to include icons and other stuff.\
Hopefully it won't take that long to make, so I'll update this when its ready.
EDIT
Its ready!
I am including two versions in this release, a glass, and a non-glass version. Just download the .zip and extract it to your usb, not in the PortableApps menu folder. To choose which version of the menu you want, go to \PortableApps\PortableAppsMenu\App\DefaultData and rename your style to Theme. Enjoy.
