I would like to show a message that basically looks like the "toast" of Outlook (or a Growl notication on OS X). I want to show that message from a node-webkit application in a way that works on OS X, Linux and Windows without any changes (if this does not work, you may skip Linux).
How could I do this?
So far I have seen that I could use node-growl, but the setup for the various operating systems is a little bit, well, clumsy.
Is there a better approach?
