Would it be possible to add a command-line option to start Snarl with no Systray icon? I'm thinking:
Which would stop Snarl without displaying the MsgBox.
This would be especially handy for deploying and using Snarl for Alerting in College / Corporate environments where you'd like to notify users of things without letting them right-click the Systray icon and close it.
This is a wonderful app. I've been praying for something like this on Windows ever since I started using Growl.
