The version with the Nixie screen is now up in Extras and should appear as an update for flipclock. I did not have a chance to get the extra signal handling code in there, as my focus is now on the new C-based version of the app rather than on the current python-driven one.

Not sure about the setting alarm for sunday when it's saturday thing, I'll try to check it out myself at some point as it sounds like a minor bug that probably won't be too hard to fix if I can figure out what's causing it.
