Does this version allow you to specify command line arguments too yet?
I am using Prism with Firefox to read my Google Apps email, so the shortcut I need to use is:
"C:\Program Files\Mozilla Firefox\firefox.exe" -app application.ini -override "C:\Users\Ian\AppData\Roaming\WebApps\iangrant.me.uk.mail@prism.app\override.ini" -webapp iangrant.me.uk.mail@prism.app
The last version I tried would only allow me to select the executable, which just launches Firefox, not the Prism version.
