[FEATURE] Create a report on reading behaviour and history

During incremental reading, you create valuable data that can be evaluated to gain insights and optimize learning strategy, such as average time spent on each document, scroll speed per document, length of reading sessions before continuing to next document, which documents you've read for a long time and in detail vs. which ones you've skipped through or dismissed from the queue before finishing.

Currently this data simply gets lost, it would be great to have an optional feature that logs when a document is opened, when it is closed, start and end scroll position and allows exporting this data in a structured format.

Based on this data, you could do your own evaluation and ie. hand this to AI for context when giving you recommendations on what to read next.
