The stats page shows your totals. The heatmap shows your patterns. But until now, there was no way to see the individual progress updates themselves - every time you opened the app and logged "page 142" or "4h 23m".
Now there is.
Every book now has a Progress History section on its detail page. It lists every individual progress update you've ever logged against that book, in reverse chronological order.
Each entry shows:
If you've read a book more than once, the history groups entries by read. Each read gets its own collapsible section with a date range and status badge ("#1 · Finished", "#2 · Reading").
The current read is expanded by default. Past reads stay collapsed but you can open them to see exactly how your previous read-through went - useful when you're comparing pacing between reads or just curious how long it took you last time.
If you've started a new read but haven't logged progress yet, you'll see "No progress logged yet for this read" rather than entries from your previous read pretending to be current.
Long histories don't push the page down forever. Each expanded read caps at a comfortable height with its own scroll. Hundreds of entries fit cleanly without dominating the page.
This was one of those features that felt missing once we noticed it. The data was always there - we just weren't showing it. Now you can see exactly where your reading time went.
