Nice concept! Here's a couple of thoughts for you:

1) My worst peeve with NOTAMs in general is all the "tower lights out
of service" NOTAMs. Provide a way to filter these out and I'll
DEFINITELY use this!

2) Allow a way to put in more than one airport at a time and get the
union of the applicable NOTAMs
