I still don’t like vertical videos. My natural field of view is landscape and portrait feels crowded and stressful. Also vertical videos have to be watched 2-3 times to see everything, because the person filming has to pan the camera so much, and they usually move too quickly. It’s like everyone forgot that a phone can be rotated.
A pill organizer, if the original containers are too large (or too numerous) to be practical. I’ve only flown domestic USA, but security has never bothered me about it.
