Nothing new to learn conceptually here — just a few genuinely useful tools that didn't fit anywhere else, plus the housekeeping that keeps years of planning work from disappearing.

The very first Top Panel, and one we skipped until now. It calculates how long a shadow an object of a given height will cast — for the Red Pin's position, at the selected date and time.

Back in Lesson 1 we covered this in one slide. Now that you've actually built Plans and Points of Interest across this whole series, it's worth a real look at what each piece does.

Tap any Plan to see its full information sheet — location, Sun/Moon/Milky Way conditions, and any photos or notes you've added. Swipe left to delete one, or tap Action to email it, add a calendar alert, or share it.

Choose what to include, then tap Start backup — PhotoPills creates a file you can email to yourself. Getting a new phone, or just being careful? Use Import backup to restore everything from that file, Dropbox, or Google Drive.

Everything else in Settings is safe to leave on its default until you have a specific reason to change it.
