- Message history archived per conversation on the SD card (HIST_ARCHIVE):
restored on boot, Older/Newer paging in threads, kept count selectable
- Settings > System > Storage: card and flash usage, breakdown by maps,
messages, trails and other, kept-per-chat setting, delete history;
reads the mounted volume and warns when the FAT partition is much
smaller than the card
- Saved trails on the card: every Save is a new file, Load opens a list
with load (framed on the map), GPX export and delete
- Diagnostics: GPS data rows, last start reason, last crash summary
- Messages restored before the clock is set show their date instead of 0s
