• Capture button now sits right under the camera view, and "Saved · N in log" appears only after the reading is really stored • No GPS fix: coordinates show a dash and the reading is marked as having no position (older versions used a sample location) • Capture and A–B marking wait until both compass and tilt sensors respond • Readings saved by older versions at the sample location are labelled unverified • A–B result now shows a side-view sketch of your two sightings, and the converter draws the A–B bearing on a compass dial • New icon and line icons
