Next update should include an interface where you can put the URL in a textbox, rather than in the coding. Or something that automatically gets it for you, if possible.
The text box should be do-able, I'll work on that, however I don't think I can do something to automatically get it for you, as the link has to include your unique facebook ID and also an authorisation key as an identifier that you're allowed access to the feed.
But I agree that a textbox would be a nice solution to at least avoid having to edit the code.
While you're at it, also let people specify how it is displayed. Like, a text box where you can use %status to insert the status. Too early for me to be able to explain properly But there would be one box where you enter the feed and another where you enter how you want it displayed (for example "[Facebook Status:] %status" in the case of Chris4).
