Grumpy, you mean if you choose "Offline" in the config tab, it would have something in the status bar to indicate that you were running offline?

Adding detection for a receipt is fairly straight forward but how would you like to be notified, something that just indicates that a receipt is present?

Just curious but where did you get the 3 months number from? I am now finished my course so that is one thing out of the way. I still have lots of stuff to work on so it won't be right away but I hope to start adding new features to dfGUI before 3 months.
