The main program screen. You'll only need to use this when adding new events or changing notification options.
This is where you edit and add new events. You can also just open the events.csv file and edit it by hand, in Excel or in a text editor, if you prefer.
This is where you set up how often you want to be notified and how far in advance of upcoming events.
This is what pops up on your screen when events are approaching.
