Nice! If you decide to add NFC sticker capability (scanning a sticker opens a checklist directly) please coordinate with the other person in this thread who might also create an app. I think the NFC data should be the equivalent of "checklist://cessna172cockpit" i.e. it should just contain a reference to the checklist, not the checklist itself. OTOH having the checklist in the NFC sticker, complete with a "last modified" date might be awsome as well, if there are multiple people who use the checklist. Assuming that the whole list even fits in a sticker. Hm...
