v1.0.0
Per-chapter read tracking for anthology EPUBs in KOReader — collections of standalone, cross-linked articles you read in any order (blog archives, essay collections). Shows which articles you've read, jumps to the next unread, and auto-marks as you finish reading one.
Install: download backlog.koplugin-v1.0.0.zip, extract it into your device's koreader/plugins/ directory, then restart KOReader. The zip extracts to a correctly-named backlog.koplugin/ folder.
See the README for usage and settings.
