Since no one else has mentioned it, I agree with all the suggestions you've made. Go for it. I was going to ask you to consider removing the seconds as well. I can see their use, but it's extreme-niche at best. Makes it so you can store the alarm time in less space too. 2 vs 3 bytes (11bits vs.17bits minimal anyway).

Any more progress on the config.ini thing affecting me yesterday? Just wondering why Hijacks gets access to the config file without a problem and your app doesn't...
