Field notes

The dashboard combines outbound links with local browser utilities: schedule files can be imported from several formats, converted into calendar data, backed up as JSON, and used for reminders. Its campus layer includes six map images, including C5 teaching-building floor plans, while shared notices and polls provide class-level coordination. The page says no backend is used for personal schedule data, but it also exposes a bookmarklet workflow for signing into the educational system and warns that any saved password remains readable in localStorage.
