For accessibility, it would be nice to add a right-click option for PortableApps in Windows Explorer.
This can be done by adding the following lines to the autorun.inf:
Shell\Read1\Command=PortableApps\PortableAppsMenu\PortableAppsMenu.exe Shell\Read1=&Start PortableApps
You can have as many pairs as you want for any options. Perhaps have a command here to launch Firefox or Thunderbird.
