Reading cockpit for the Marvel Unlimited web reader: recently read, bookmarks, status, page progress (metadata only). LONGBOX is your reading cockpit next to the official Marvel Unlimited web reader. The desktop reader lacks this organizing layer — LONGBOX adds it without changing how you read. • Auto-tracks every issue you read — zero clicks, follows "Read Next" binges too. • Per-issue page progress. • Dashboard: recently read, cover wall, bookmarks, status (reading/want/finished), series progress, search & filters, "where was I" notes. • Popup quick access to keep reading. • Export/import (JSON), German & English. Privacy first: LONGBOX stores only metadata (title, issue id, cover URL, page number, notes) locally on your device. It does not read or store comic images, transmits nothing, tracks nothing, and circumvents no copy protection. You keep reading in the official reader. Note: LONGBOX is an unofficial, independent tool and is not affiliated with Marvel or Disney.
